We rented form Paradise and they had no issue with us taking the ferry. It only takes a couple of hours to go around the island, great beaches, views etc. But.......it takes a while to load both directions so just be aware is can be a wait. If you take the walk on ferry, there are places to see when you arrive, shopping etc and great places to eat lunch. You can take taxis so any of the snorkeling beaches if you take the walk on ferry. This last time we were with friends on a 48 ft cat after we left St Thomas and moored in the WSJ bay then off to the BVI's. An amazing trip! Enjoy!
