I've sailed the BVI's several times and vacationed both on St. Thomas and St. Johns and I really like the advice of Robinson above. My first choice would be to charter a catamaran and choose several of the BVI's over the course of the week, but that would cost more than $3500. St'. Thomas really doesn't have a lot of night life (The Green Room across the street from the ferry terminal has a good happy hour but after one or two of those....) and it's nowhere near as pretty and unspoiled as St. Johns is and there's a lot more crime on St. Thomas. The eco-resort on St. Johns at the far end of the island from the ferry is really nice but unless the one at Cinnamon Bay has been updated recently, I wouldn't recommend it. Someone else described the tent villages, with hard floors and some hard walls, with other walls of canvas and a tent roof. They're very well done but not fancy, but since the temperature is always in the 70's or 80's you'd be very comfortable. It's not like you're tenting out and have to go for a walk through the jungle to use the bathroom. It's like being in a house and leaving the windows open at night so you can hear the sounds and have plenty of fresh air. But his idea of renting a house out there sounds great too. That could be your headquarters and you can snorkle or scuba dive or charter a boat/ferry over to Jost van Dyke or even way up the Sir Francis Drake Channel to the Bitter End YC, and hike or just hang out out on beautiful, unspoiled beaches or rent a sailboat or motorboat for a day trip. They even have a couple of bars near the ferry if you want a taste of more traditional night life, but it's not like a big city night club, more like a place to have a drink on the beach. You really can't go wrong. Have fun!
