A valid passport is strongly recommended for all cruises, even though some cruises departing from and returning to U.S. ports (closed-loop cruises) allow travel with a birth certificate and government-issued photo ID.
Having a passport provides greater flexibility and protection in case of emergencies or unexpected travel changes, such as needing to return to the U.S. by air from a foreign port. A passport helps ensure a smoother and more secure travel experience.
All cruise travelers are recommended to obtain or renew their passport to avoid potential complications.
