Hi we are going on Harmony of the seas in August. We have a 14 and 8 yr old. Our youngest has special needs so when we stop in St Thomas it will be from 12-8 pm. We would like to find a less crowded beach or more private beach to go to. I have been doing a lot of research and it seems that St John might be a great area to go to. We would like to go on our own like rent a car or take a ferry over. Is this possible to go to for 4 hours and get back in time to port? Suggestions?
