Guests do have the option to remain onboard the ship while in port, and it is at each guest's discretion whether to disembark while in Cuba. Guests who choose to remain onboard the ship do not need a Cuban visa. You will not have to complete the visa forms at the pier and will not have to pay for visa processing. However, all guests including minors, and even those that choose to remain onboard in Cuba, are required to have a passport book valid for at least 6 months after the date of their Cuba sailing and to complete the Travel Certification document prior to boarding the vessel. You must bring two printed, completed copies of the document, for each guest, to the pier on embarkation day.
