What is the most private Caribbean vacation for a group?

The most private Caribbean vacation for a group is a whole-property buyout — a private island, a staffed villa estate, or an entire crewed yacht. All three give one group exclusive use with no other guests. The yacht is the one most people forget. A crewed catamaran chartered for six to twelve guests belongs entirely to the group, and unlike a fixed villa it can move to an empty anchorage the moment a beach gets busy. Private islands in the BVI deliver total seclusion but hold a group in one spot; a yacht trades a fixed address for a new one each day. For groups that want privacy and variety at once, the boat wins. Plan a private Caribbean charter.
