The cruise might have ended, but there are still some great activities to enjoy in the area. If you flew into this port, be mindful of your departure flight time and plan accordingly.


U.S. Citizens
Proper travel documentation is required at embarkation and throughout the cruise. Even though a guest has completed registration using Online Check-in, it is still the responsibility of the guest to present the required travel documents at the time of embarkation. Guests should check with their travel agent and/or government authority to determine the travel documents necessary for each port of call. Any guest without proper documents will not be allowed to board the vessel and no refund of the cruise fare will be issued. Royal Caribbean assumes no responsibility for advising guests of proper travel documentation.
Except where it is a mandatory requirement, Royal Caribbean highly recommends that all guests travel with a passport book. The passport book must be valid for at least six months beyond the completion of travel. This will enhance the debarkation experience as delays may be expected upon return to the United States for those without one. Additionally, this will enable guests to fly from the United States to meet their ship at a foreign port should they miss their scheduled port of embarkation and allow guests who must disembark the ship before their cruise ends, due to an emergency, to fly back to the United States without significant delays and complications.
U.S. Domestic Cruises
For certain cruises that begin and end in the same U.S port, the following WHTI-compliant documents are acceptable for cruise travel (please see below for travel document requirements for voyages visiting Colombia, Greenland, Martinique and Panama). *
* Travel document exceptions for U.S. domestic cruises that begin and end in the same U.S. homeport, calling on the following ports of call:
* Travel document exceptions for U.S. domestic cruises that begin and end in different U.S. homeports: Mandatory requirement for passport book or passport card (valid for at least six months beyond the completion of travel).

ETA – UK Electronic Travel Authorization
Please note:
ETiAS - European Travel Information and Authorization System
Official website: https://travel-europe.europa.eu/etias_en
ETIAS is an electronic system that is being implemented in Europe to screen travelers before they enter the Schengen Area. It's an authorization, not a visa, for visa-exempt individuals (including U.S. and Canadian citizens), travelling to most European countries.
Please note: The projected implementation timeframe for ETIAS is last quarter of 2026. Additional information will be provided once more details about the start date, requirements and the application process have been established.
Air Travel
All persons are required to carry a valid, unexpired U.S. passport for air travel to or from the United States, Canada, Mexico, the Caribbean and Bermuda. The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory (Puerto Rico and the U.S. Virgin Islands: St. Thomas, St. John, and St. Croix).
Effective May 7, 2025, the U.S. Department of Homeland Security will require every state and territory resident to present a REAL ID-compliant driver’s license or another acceptable form of identification, such as a passport or enhanced driver’s license, to go through airport security and board a flight within the U.S. If you will be flying to one of our cruise homeports within the U.S. on/after this implementation date, please ensure you have an acceptable document for your air travel. Visit www.tsa.gov/real-id for more information.
Note: All guests must still have WHTI-compliant travel documents (proof of citizenship and/or appropriate visas) in order to cruise.
Names on Travel Documentation
It is important that the guest's full name (first name and last name) on the cruise and airline tickets be the same as the guest's unexpired, government-issued photo ID that will be used for travel identification. In the event of a different name on the cruise/airline ticket and the guest's photo ID because of a marriage, divorce or a legal name change, documentation (original or clear, legible copy) supporting this change is required at embarkation, such as a marriage certificate, marriage license or legal name change court document. Failure to bring documentation bridging the name differences could result in denial of boarding.
Traveling with Minors
When traveling with a minor where one parent or both parents or legal guardians are not cruising, we strongly recommend bringing an original, signed letter from the absent parent(s) or legal guardians authorizing the minor to travel with you. If there is no second parent with legal claims to the minor (due to sole custody, deceased, etc.) other relevant paperwork, such as a court decision, death certificate, birth certificate naming only one parent, would be useful to bring in place of a signed letter. This will expedite processing by the Department of Homeland Security.
Citizens of U.S. Territories and Commonwealth
Guests will follow the same travel documentation requirements. U.S. Territories and Commonwealth include: Puerto Rico, Guam and the U.S. Virgin Islands (St. Thomas, St. Croix and St. John), America Samoa, Swains Island and the Commonwealth of the Northern Mariana Islands.
Passport – The hassle-free way to travel
For some voyages, traveling with a passport book is a requirement. Even when not required, we strongly recommend traveling with a passport. You will be traveling internationally, a passport (book) is the best document for hassle-free travel. Not only will a passport enhance your embarkation experience, it will also get you through the customs and immigration processing faster at debarkation.
If you are looking for something more accessible, a passport card will also provide a speedy embarkation and debarkation experience. Passport cards are a nice alternative to passport books for sea travel to countries within Western Hemisphere Travel Initiative (WHTI) countries and may also be used as REAL ID (for domestic air travel purposes).
In the event an emergency arises, a passport book is the only acceptable document for flying back home from overseas.
Note: A passport (book or card) must be valid for at least six months after the last day of the cruise.
