Jim is correct. Other points new where that EVERYONE was required to go through immigration, including US Citizens before the ship was cleared for disembarkation in St. Thomas, and for final disembarkation, which meant we had to get up early even if you weren't planning to go ashore to stand in a line to show our passports onboard the ship and be checked off a list. You will also notice the USCG escorting the ships, or at least watching them very closely when both entering and leaveing port and while in port. We saw this too in Nassau and St. Thomas as well as Port Canaveral, too. If you don't have passports, it is still a good item to purchase now. The St. Thomas immigration issue was new from November, too.
