In most cases, a valid U.S. passport is required when taking a cruise. Though some "closed loop" cruises (those that begin and end at the same U.S. port) may not require a passport, we recommend bringing yours in case of an emergency, such as an unexpected medical air evacuation or the ship docking at an alternate port. Your cruise company may require you to have a passport, even if U.S. Customs and Border Protection does not. Additionally, we recommend you travel with a passport while in port in case of emergency.
Please be advised that securing and bringing the required identification and travel documents (by governments, cruise lines, air lines, etc.) are solely the responsibility of each guest. We are unable to provide refunds for guests who do not possess the necessary documentation.
For up-to-date travel documentation requirements, please visit: U.S. Department of State.
Additional travel documents may be required for international travel, and we recommend all travelers confirm the entry requirements for all countries prior to departure. For more information, visit: What documentation is required for non-U.S. travel?
