There is no question if you can find the boat you want on St. Thomas that is the route to go. There are limited boats available for charter on St. Thomas. Maybe we should be keeping the St. Thomas boats a secret? The only possible downside of the issues with chartering from anyone with limited inventory is you are stuck with STT as an airport. A big plus for many but less desirable on the days and timeslots where US departure can be a major zoo of the cruise ship type.
