Sounds like pickup at Crown Bay may be best? I don't think we can guarantee that they can make the 5pm ferry with a 3:40 landing and a 40 min taxi ride. If we pick them up, we could either drop anchor in Christmas Cove or St. John depending on our timing? We are mainly planning to travel to USVI in case they have delays. We don't want the hassle of booking another room and leaving them alone for a night.
