Service Dog on a Cruise Ship: The Rules, the Ports and 9 Cruise Lines Compared

A service dog on a cruise ship is covered by federal law, and every major cruise line sailing from the United States says it welcomes one. The rule the lines answer to says they must take your word that the dog is a service dog, let him go anywhere passengers can go, and let you bring his food aboard at no charge. That part is simpler than most people expect.

What is not simple is everything around the ship. Each cruise line sets its own paperwork deadlines, and several ask for more than the federal rule does. Each country the ship calls at has its own animal import law, and that is where service dogs actually get stopped. Then the Centers for Disease Control and Prevention has a say in whether the dog gets back into the United States at the end.

Mr. Big and I never took a cruise. I would have loved to. So this article is built from the federal rules and from what nine cruise lines publish about service dogs, all read again in September 2026, not from my own sailings. Where I am telling you something from experience, I will say so.

Last updated: September 2026

The short answer

Which rulebook you are standing in

There is a line in my flying with a large service dog piece that I keep coming back to: knowing which building you are standing in tells you which rule applies. A cruise ship is the fourth building.

In a shop, restaurant or hotel, the rules are the Department of Justice’s, and they are laid out in the ADA service dog laws.

On a plane, it is the Air Carrier Access Act and 14 CFR Part 382.

On a bus or train, it is the Department of Transportation’s rule for ground transportation, which I wrote up in service dogs on buses and trains.

On a cruise ship, it is two rules at once. The Department of Transportation wrote one just for passenger vessels, 49 CFR Part 39, and the Justice Department’s shop-and-hotel rule applies on board as well. The Justice Department said so in plain words when it rewrote its rules in 2010:

“Vessels operated by private entities primarily engaged in the business of transporting people and that provide the goods and services of a public accommodation are covered by this regulation and the Department of Transportation’s passenger vessel rule, 49 CFR part 39.”

Its own example was “a cruise ship that sails from Miami to one or more Caribbean islands.”

The foreign flag does not get the ship out of it

Almost every large cruise ship is registered in another country. That does not take it out of the federal rule. Part 39 answers the question directly:

“If you are the PVO of a foreign-flag passenger vessel, this Part applies to you only if your vessel picks up passengers at a port in the United States, its territories, possessions, or commonwealths.”

PVO means the passenger vessel owner or operator. If your cruise starts in Miami, Galveston, Seattle or any other U.S. port, the rule applies to the ship you are boarding.

The Supreme Court settled the same question for the ADA itself in 2005, in a case brought by passengers with disabilities against Norwegian Cruise Line. The Court said that although the ADA’s definitions “do not expressly mention cruise ships, there is no doubt that the NCL ships in question fall within both definitions.” Justice Kennedy’s opinion concluded that “except insofar as Title III regulates a vessel’s internal affairs, the statute is applicable to foreign-flag cruise ships in U.S. waters.”

The “internal affairs” limit is mostly about permanent changes to how a ship is built. A service dog policy is a policy, not a piece of steel. I have not found a court case that applies that decision to service animals specifically, so I will say it the way it is: the reasoning points toward coverage, and the Department of Transportation’s rule does not leave room for doubt.

What the federal rule actually says

The service animal section of the passenger vessel rule is five short paragraphs, and I think every handler thinking about a cruise should read it once. Section 39.91 says the cruise line “must permit service animals to accompany passengers with a disability,” and then:

“You must permit the service animal to accompany the passenger in all locations that passengers can use on a vessel, including in lifeboats.”

On food, it says the line must let you bring a reasonable quantity aboard “at no additional charge,” and on a ship with cabins, “reasonable refrigeration space for the service animal food.”

And on proof, this is the sentence that matters most:

“You must accept the following as evidence that an animal is a service animal: Identification cards, other written documentation, presence of harnesses, tags, and/or the credible verbal assurances of a passenger with a disability using the animal.”

Read the “and/or” in that list. A card is one way to show it. A harness is another. Your own word is another, and the line must accept it.

Two more sections back that up. Section 39.33 says a cruise line “must not require a passenger with a disability to have a medical certificate as a condition for being provided transportation on your vessel.” Section 39.35 says it “must not require a passenger with a disability to provide advance notice” of the fact that they are traveling, unless they are asking for particular services “that in order to be provided need to be arranged before the passenger arrives to board the vessel.”

Section 39.37 adds that for “particular auxiliary aids and services,” the line “may request reasonable advance notice to guarantee the availability of those aids or services.”

One more difference from the shop rule, and it is the same one I found on buses and trains. The Justice Department limits service animals to dogs, with a separate provision for miniature horses. The Department of Transportation’s vessel rule still defines a service animal as “any guide dog, signal dog, or other animal individually trained to work or perform tasks for an individual with a disability.” In practice every cruise line I read talks only about dogs, and so does this article.

What nine cruise lines actually ask for

I read the service animal pages of Royal Caribbean, Celebrity, Carnival, Norwegian, Princess, Holland America, MSC, Disney and Virgin Voyages. Every one of them accepts trained service dogs. Where they differ is how much notice they want and what they want to see before the dog boards.

Here is what each line says, in its own words where it matters.

Royal Caribbean and Celebrity: the closest to the rule

These two belong to the same company and publish nearly the same page. It is the only wording I found that lines up with the federal rule on proof:

“Evidence that a dog is a service dog is helpful but not required (such as identification cards, other written documentation, presence of harnesses and/or tags or the credible verbal assurance of the person with a disability using the dog).”

Their deadline is tied to one thing, the relief area: “Please notify our Access Department at time of booking but no later than 30 days prior to sailing if a service dog relief area is needed.” The relief areas are four feet by four feet, filled with cypress mulch and shared with any other service dogs on board. Royal Caribbean says sod can be provided for sailings from the U.S. if ordered in advance and available, and that Central Park on its Oasis class ships is not a relief area. Celebrity says the same about The Lawn Club on its Solstice Series ships.

Dogs are allowed “in all public areas, including dining venues,” on a leash or harness, and not in pools, whirlpools or spas. Both lines say a cleaning fee may be charged to your shipboard account. Royal Caribbean has also stopped accepting emotional support animals: “We will no longer have emotional support animals onboard.”

Carnival: a one-week deadline and some port rules at the gangway

Carnival asks for your documents “no later than one week prior to your sailing,” sent to its Guest Access team, and says you must hand-carry the originals on embarkation day. The list starts with a “Current Vaccination Record (must include rabies vaccine and microchip number)” and a “CDC Dog Import Form Receipt.” There is also a Service Animal Form.

Carnival accepts working service dogs only: “Pets, or service dogs in training, are not allowed aboard.” On board, dogs are not permitted on furniture, in food preparation areas, pools, whirlpools, saunas or steam rooms, may go in all other public areas including dining areas on a leash, and may not be fed in the dining room, buffet or specialty restaurants. A relief area is set up “in a non-guest traffic area of the ship by our team,” and if your dog prefers a particular material, Carnival asks you to bring it and tell them before the cruise.

Two port rules on Carnival’s page reach back onto the ship. If your itinerary includes Grand Turk, you need an import license from the Turks and Caicos government, and:

“restricted‑breed service dogs, or any service dog without all required documentation, will not be permitted to board the ship at embarkation.”

That is a port’s breed rule applied at the gangway in Florida, and if your dog looks like Mr. Big, it matters. Breed has nothing to do with whether a dog is a service dog under U.S. law, which I wrote about in can a pit bull be a service dog. It can still decide whether a particular itinerary is open to you.

And for Belize, Carnival says all service dogs must travel with the necessary documents and permits “regardless of whether the dog will disembark in Belize.” Belize requires an import permit from its Agricultural Health Authority.

Norwegian: two weeks, a health certificate, and two ports where the dog stays aboard

Norwegian says “All guests traveling with service animals must book at least two weeks in advance to allow enough time to check with each port of call.” It asks for “copies of the dog’s current vaccination records that show all shots are up-to-date (including Rabies), as well as a USDA or International Health certificate.”

Norwegian names two places where a service dog cannot go ashore. Jamaica: “due to government restrictions in Jamaica, guests traveling with a service animal will not be able to go ashore.” And Iceland, when the ship is only calling there. A relief box is provided. One line on the page is worth noticing: guests “are responsible for bringing all food, medication and life jacket for the dog.”

Princess: a description of the task, in writing

Princess welcomes “service animals that are trained to perform tasks including the support of vision, hearing or other specific needs.” To start, you email its access office with your booking number, ship and sailing date, “with a brief description of the service animal, including the specific work or task the animal has been trained to provide.” Princess provides a relief area and says the types of litter material “are limited and may vary by ship.” Emotional support animals “are not permitted on Princess ships.”

Holland America: vaccinations before you sail

Holland America says “To board the ship, your service animal must have current vaccinations,” with records sent to its Guest Accessibility Department “prior to your departure.” It does not permit “therapy/companion animals.” If a port turns your dog away, it says “the staff and crew will work with you to determine what actions may be possible to allow you to visit the port without your service animal.” Except in that situation, you “may not leave your service animal unattended on the vessel or in your stateroom at any time.”

MSC: the longest deadline and the most paperwork

MSC wants its Accessibility and Medical Request Form “60 days prior to sailing,” and six months ahead for the World Cruise. Its list:

• “Service Dogs must be 6 months of age and have a microchip.”
• “A written explanation of what specific tasks the animal has been trained to perform must be provided.”
• “Veterinarian certificate stating that the animal is healthy.”
• Department of Agriculture permits and CDC documentation as each port requires.

MSC also says that if anything goes wrong with the dog’s documents at a port, “all related costs for either the quarantine of or re-export of the dog will be the dog owner responsibility.” It provides a relief area with mulch and keeps dogs out of pools, spray parks and the spa.

Disney: 30 days and the port permits up front

Disney says “Guests must notify Disney Cruise Line 30 days prior to their sail date,” using its Special Services Information Form, and “Copies of completed permits for each port of call must be sent to Disney Cruise Line Special Services prior to the sail date.” It warns that getting those permits “can take weeks or months, and some countries may not allow dogs to enter at all.” Dogs are “welcome in most locations on board,” are not allowed in the pools or wet play areas, and may not be left alone in a stateroom. Some shore excursions may not allow dogs.

Virgin Voyages: 14 days and import permits

Virgin asks for documents “at least 14 days prior to the Sail date,” and says you “must obtain the required import permits per the regulations of each country we visit.” Every ship has a relief area “Forward on Deck 7.” Virgin does not accept dogs whose “sole function is to provide comfort or emotional support,” and says damage to a cabin caused by a service animal is charged to your account.

Where the lines ask for more than the rule

Put the table next to Section 39.91 and some differences stand out. I am going to state them plainly and not guess at the reasons.

• A written description of the dog’s task. Princess asks for one in the email that starts your request, and MSC says one “must be provided.” The federal rule lists your verbal assurance as enough.
• Deadlines to sail with the dog at all. MSC’s 60 days, Disney’s 30, Norwegian’s two weeks, Virgin’s 14 days and Carnival’s one week. The rule allows a line to ask for notice to arrange particular services. It does not allow requiring notice just because you are traveling with a disability.
• Health and vaccination papers to board, not just to go ashore. Carnival, Norwegian, Holland America and MSC. The rule bars requiring a medical certificate from the passenger. It does not mention the dog’s vaccination records, and the lines tie those records to the ports and to the CDC.
• A breed rule at the gangway. Carnival on Grand Turk itineraries, which Carnival says comes from that port’s import license.

That is a mismatch between what the lines publish and what the federal rule says, and I am going to leave it as one. Some of it may be the lines protecting themselves from a port refusing the dog. That does not change what the rule says.

My practical view, for what it is worth: send the paperwork anyway. Sailing day is not the day to argue about it with a line of people behind you at the terminal, and the vaccination records are the same records a port will want. Know the rule so you have something to stand on if the line goes further than its own page, or turns you away.

The ports: where service dogs actually get stopped

Everything above is about the ship. The moment you walk down the gangway, you are in another country, and that country’s animal import law decides whether your dog comes with you. The ADA does not reach the pier in Cozumel or Nassau. The federal rule says so itself, in Section 39.91(e):

“If the legal requirements of a foreign government (e.g., quarantine regulations) do not permit a service animal to disembark at a foreign port, as a PVO you may require the animal to remain on board while its user leaves the vessel. You must work with the animal’s user to ensure that the animal is properly cared for during the user’s absence.”

Every cruise line I read puts the port paperwork on you. Carnival: “Documentation that allows your service dog to board the ship does not guarantee permission to go ashore in ports of call.” Royal Caribbean: guests “are responsible for obtaining all required documents for the animal to depart the ship in ports of call and at the final destination.” Holland America: “All documentation and immunization requirements are established by government authorities and not by Holland America Line.”

What the ports ask for varies a lot, and some of it will surprise a handler used to the ADA. Canada is a good example. Its border agency defines an assistance dog as one that “has been certified and trained by an organization accredited by the International Guide Dog Federation or Assistance Dogs International.” It also says assistance dogs “do not include therapy animals, companionship animals, emotional support animals, or comfort animals.” An owner-trained dog like Mr. Big, fully legal as a service dog in the United States with no certificate at all, may not meet Canada’s definition. I wrote more about how other countries treat service dogs in the ADA and other countries and traveling internationally with a service dog.

There is a simple way to hold all of this in your head. U.S. law governs the ship. The port governs the pier. A registration card sold online will not change either one.

If your dog has to stay on board

Plan for this before you book, not in port. The lines’ own pages say the crew will not look after the dog for you. Royal Caribbean says “the ship’s staff is not required to care for the dog, nor can the dog be left in the stateroom unattended.” Holland America says its crew “will work with you to determine what actions may be possible.” In practice that usually means one of three things: you stay aboard with your dog that day, someone you trust in your party stays with him, or you choose an itinerary where he can go ashore at every stop.

Ask the line before you pay which of your ports will let the dog off, and what the arrangement is on the days he cannot go.

Coming home: the CDC rule at the end of the cruise

Since August 2024, every dog entering the United States needs to meet the CDC’s dog import rule, and that includes a service dog coming back from a cruise. For a dog that has only been in low-risk countries, the CDC says the one form you need is the CDC Dog Import Form, and the dog must appear healthy, be at least six months old, and have a microchip a universal scanner can read.

The part that matters most for cruises is which countries the ship visits. The CDC keeps a list of countries at high risk for dog rabies. As of September 2026 it includes Belize, Colombia, Cuba, the Dominican Republic, El Salvador, Guatemala, Haiti and Honduras. Mexico, the Bahamas, Jamaica, the Cayman Islands and Canada are not on it. The list changes, so check it the week you book.

Here is the good news, straight from the CDC’s own questions and answers:

“A service dog is not considered to have been in a high-risk country if it remains on a cruise ship (does not disembark) when the ship stops at a port in a high-risk country.”

If your U.S.-vaccinated dog does go ashore in a high-risk country, the CDC says he needs “a valid (unexpired) Certification of U.S.-issued Rabies Vaccination Form and the CDC Dog Import Form receipt (that lists the port where the ship will arrive).” A dog vaccinated outside the United States needs more, including a rabies titer from a CDC-approved laboratory.

One detail to know: for these seaport rules, the CDC uses the airline definition of a service dog, the one in 14 CFR 382.3 that I explain in the flying article. It leaves out emotional support animals and dogs in training.

Where does a service dog go to the bathroom on a cruise ship?

This is one of the most searched questions about cruising with a service dog, and the answer is a box. Every line I read provides a relief area of some kind:

• Royal Caribbean and Celebrity: four feet by four feet, cypress mulch, shared with any other service dogs on board. Royal Caribbean offers sod on U.S. sailings if ordered ahead and available.
• Carnival: set up by the crew in a non-guest area. Bring your dog’s preferred material if you have one, and tell them before the cruise.
• Norwegian: “A relief box will be provided.”
• Princess: a relief area with litter material that is “limited and may vary by ship.”
• MSC: a relief area with mulch.
• Virgin Voyages: a designated area forward on Deck 7.

If your dog has only ever gone on grass, a box of mulch on a steel deck is a new request. Practice at home on the same material before you sail, the way you would practice anything else you want him to do on command in a strange place.

Pools, dining rooms, lifeboats and your cabin

Pools. Royal Caribbean, Carnival, MSC and Disney all keep service dogs out of the pools, and most name whirlpools and spas too, citing health rules. The Justice Department’s guidance takes the same line on land: the ADA “does not override public health rules that prohibit dogs in swimming pools. However, service animals must be allowed on the pool deck and in other areas where the public is allowed to go.”

Dining. Royal Caribbean, Celebrity, Carnival and MSC all say service dogs may go into the dining venues. The Justice Department is clear that a business is “not required to allow an animal to sit or be fed at the table,” and Carnival asks that dogs be fed in your stateroom, not in the restaurants.

Lifeboats. The federal rule says your dog goes where you go, “including in lifeboats.” Norwegian asks you to bring a life jacket for the dog. That is worth doing on any line.

Your cabin. Royal Caribbean, Holland America, MSC and Disney all say you cannot leave the dog alone in the stateroom. That matches the Justice Department’s answer for hotels: “the dog must be under the handler’s control at all times.” Plan your days on board around that. Most lines also expect the dog on a leash or harness in public areas, which I cover in is a leash necessary for service dogs.

Behavior. Royal Caribbean and Celebrity say a dog whose behavior “creates a fundamental alteration or a direct threat to safety” may be “denied boarding or removed from the ship along with the owner at the guest’s expense,” and list examples including “growling, barking excessively, initiating unsolicited contact.” A cruise is days of crowds, noise, elevators, buffets and children in close quarters with no way off. If your dog would struggle with a busy mall for eight hours, he will struggle on a ship. The honest test is the one I describe in the public access test: be your own harshest judge before someone else has to be.

ADA information cards: good to have on hand when it gets difficult

Having just said nobody can demand a card, here is the one card I do think is worth carrying, and the difference matters.

A registration card or an ID claims to prove something about your dog. It proves nothing. An ADA information card does something else entirely: it puts the law in the other person’s hand. It is a handout, not a credential.

On a ship that difference is practical. The person questioning your dog might be a new crew member on their first contract, a terminal worker, or a guest services supervisor who has been told the wrong thing. You will get further handing them a small card to read than explaining federal regulations at the gangway. That is when circumstances turn problematic: the crew member who is sure dogs are not allowed in the dining room, the supervisor who wants papers you were never asked for. That is what the card is for.

Hand it over when the conversation stalls, not as your opening move. Leading with a card invites the idea that you think a card is required, and you do not.

One honest note. The cards quote the Justice Department’s wording, which is one of the two rules that apply on a cruise ship. The Department of Transportation’s vessel rule goes further, since it says the line must accept your verbal assurance. A crew member who reads the card will come away with the right answer either way.

I wrote more about how and when to use them in what to do if your service dog is denied access.

That is the only affiliate link in this article. No cruise line, travel company or registry pays me anything, and nothing else here is linked for money.

Emotional support animals and dogs in training

Emotional support animals are not service animals under the ADA, and the Justice Department says they “do not qualify as service animals under the ADA.” The Department of Transportation’s vessel rule requires an animal “individually trained to work or perform tasks.” Every cruise line I read that addresses emotional support animals turns them away: Royal Caribbean, Celebrity, Carnival, Norwegian, Princess, Holland America and Virgin Voyages. I found no law that requires a cruise line to take one. The difference between the two is covered in emotional support animal vs. service dog.

Service dogs in training are a harder no than they are on land. Carnival says so directly. The CDC’s cruise provisions use a definition that leaves them out. And no federal rule gives a dog in training a right to board. If your dog is still in training, what the law does and does not give you on land is in can service dogs in training go anywhere. For a cruise, wait until he is finished.

When it goes wrong at sea: where the complaint goes

The federal rule builds in a complaint route that most passengers never hear about.

On the ship, ask for the Complaints Resolution Official. Section 39.101 says the line must designate one or more of them and “make a CRO available for contact on each vessel and at each terminal that you serve.” That can be in person or by phone at no cost to you. The line must tell you about the CRO if you raise a concern about disability discrimination.

If they refuse to let you or your dog board, Section 39.25 says the line must give you “a written statement of the reason for the refusal,” and must provide it “within 10 calendar days of the refusal.” Ask for it.

Afterward, complain in writing. Under Section 39.105, the line must respond to a written disability complaint, and must make “a dispositive written response to a written disability complaint within 30 days of its receipt” that admits or denies a violation. The line does not have to answer a complaint sent more than 45 days after the incident, so do not wait. Carnival publishes an ADA contact on its own page: 1-800-438-6744, extension 70025.

The federal government. Section 39.109 says “The Department of Justice investigates complaints and conducts reviews or other inquiries into the compliance with this Part of PVOs that are Title III entities.” You can file with the Justice Department through ADA.gov. It has acted before. In July 2015 it announced an agreement with Carnival Corporation covering Carnival Cruise Line, Holland America Line and Princess Cruises, with a civil penalty of $55,000 and “$350,000 in damages to individuals harmed by past discrimination,” plus ADA officers on each ship to resolve problems at sea.

Write down names, times and exactly what was said, the way I describe in what to do if your service dog is denied access. It matters just as much on a ship as in a restaurant.

Before you book: a short checklist

• Pick the itinerary before the line. Check every port’s animal entry rules, and the CDC high-risk list, first.
• Read your line’s own service animal page and note its deadline. MSC’s is 60 days.
• Get the port permits early. Disney and Virgin both warn they can take weeks or months.
• Vaccination records, rabies certificate and microchip number in a folder, originals and copies.
• CDC Dog Import Form submitted before you sail home, listing the port where the ship will arrive.
• Relief practice on mulch or whatever your line uses.
• A life jacket for the dog, and his food for every day plus a few extra.
• A plan for the port days when he has to stay aboard.
• Two answers ready. Yes, he is a service dog. And his task, in one sentence.
• An information card in your pocket, and the words “Complaints Resolution Official” if you need them.

Frequently asked questions

Can I bring my service dog on a cruise ship?

Yes. Every major cruise line sailing from a U.S. port accepts trained service dogs. The Department of Transportation’s passenger vessel rule, 49 CFR 39.91, requires the line to let a service animal go with you anywhere passengers can go, including the lifeboats, and to let you bring the dog’s food aboard at no extra charge.

Do cruise lines require papers for a service dog?

The federal rule says a cruise line must accept identification cards, other documents, a harness or tags, or your credible verbal assurance as evidence that the dog is a service dog. In practice many lines ask for vaccination records, a health certificate or a written description of the dog’s task before boarding, and every line puts the port paperwork on you.

How far ahead do I have to tell the cruise line about my service dog?

It depends on the line. Royal Caribbean and Celebrity ask for 30 days if you need a relief area. Carnival wants documents one week before sailing, Norwegian two weeks, Virgin Voyages 14 days, Disney 30 days and MSC 60 days. Port import permits can take much longer than any of these, so start early.

Where do service dogs go to the bathroom on a cruise ship?

In a relief area the cruise line sets up, usually a box of mulch on an outside deck or in a crew area. Royal Caribbean and Celebrity use four-foot by four-foot boxes of cypress mulch shared with other service dogs. Carnival lets you bring your dog’s preferred material. Practice on the same surface at home before you sail.

Can my service dog get off the ship at every port?

Not always. Each country decides whether an animal may come ashore, and some say no. Norwegian names Jamaica as a port where guests with a service animal cannot go ashore. The federal rule lets the line keep the dog on board when a foreign government will not allow it off, and requires the line to work with you on the dog’s care that day.

Can an emotional support animal go on a cruise?

No. Emotional support animals are not service animals under the ADA or the Department of Transportation’s vessel rule, and every major cruise line that addresses them turns them away, including Royal Caribbean, Carnival, Norwegian, Princess and Virgin Voyages. No law I found requires a cruise line to accept one.

Can a service dog in training go on a cruise?

Generally not. Carnival says service dogs in training are not allowed aboard, no federal rule gives a dog in training a right to board a cruise ship, and the CDC’s service dog provisions for cruise ships use a definition that excludes dogs in training. Finish the training first.

Does the ADA apply to cruise ships that fly a foreign flag?

Yes, in U.S. waters. The Supreme Court held in 2005 that Title III of the ADA applies to foreign-flag cruise ships in U.S. waters except where it would regulate the ship’s internal affairs, mainly its physical structure. The Department of Transportation’s vessel rule separately covers any foreign-flag ship that picks up passengers at a U.S. port.

Is a service dog allowed in the pool on a cruise ship?

No. Cruise lines keep service dogs out of pools, whirlpools and spas, citing health rules, and the Justice Department says the ADA does not override public health rules that bar dogs from swimming pools. Your dog can still go with you on the pool deck and in the other public areas of the ship.

Will my service dog need papers to come back into the United States?

Yes. Every dog entering the U.S. needs to be at least six months old, microchipped, and covered by a CDC Dog Import Form. If your U.S.-vaccinated service dog goes ashore in a country on the CDC’s high-risk list, he also needs a valid Certification of U.S.-issued Rabies Vaccination Form. A dog that stays on the ship at a high-risk port is not counted as having been there.

Which cruise line is easiest with a service dog?

On paper, Royal Caribbean and Celebrity come closest to the federal rule, because they say evidence is helpful but not required and tie their 30-day deadline to setting up a relief area. In practice the itinerary matters more than the line, because the ports decide where your dog can go ashore and what paperwork you need.

Should I carry an ADA information card on a cruise?

It is not required, and no cruise line may make you produce one. But a small card that quotes the access rules is useful when a crew member or terminal worker will not listen, because they can read the rule instead of arguing with you. Keep it for when the conversation stalls, and never confuse it with a registration or ID card.
