For Cruises + International Travel
ADDITIONAL GUEST INFORMATION, SUCH AS PASSPORT DETAILS, MAY BE REQUESTED, DEPENDING UPON TRIP TYPE.
A valid passport is required for every guest participating in international air and land travel. If you are cruising on a closed-loop cruise (meaning you start and end in the United States), you may only be required to have a birth certificate and ID. We highly recommend, however, that all guests have a valid passport book when cruising in case of an emergency, such as an unexpected medical air evacuation or the ship docking at an alternate port.
