My sister lives in St Thomas, so Im a bit familiar with this port. Walk over to "Tickles" restaurant and theres a water taxi to Water Island. You can see the ship from this island. Super close, and theyre very good at getting you back on time. No taxis needed, nor traffic to worry about. If you google St Thomas webcams, I think theres still a live webcam of Water Island. Enjoy! Its my favorite island.
