X 2 on a driving school. Might break the budget a tad but still worth it.
My wife and I are looking to check out this place in Costa Rica called witch rock surf camp. Might be a fun experience if you guys are active. Reviews all seen positive if you ever wanted to learn how to surf.
My brother and i took our wives to St. John a few years ago and it was the best vacation i ever had. We rented a small house for the week and did nothing but beach hop and enjoy the sun, sand and surf. The locals were very nice and we bought everything we needed for the week on St. Thomas and brought it over on the ferry.
