In St. Maartin, we've done the 12-Metre Regatta (which was a blast!!!) and the "Under 2 Flags" tour (which was okay).
In St. Thomas, we've done the "St. John tour" and the "St. Thomas tour" which were both pretty cool. The "St. John Island" tour was cool because you take a ferry over to St. John and then tour the island. I know we stopped at the sugar mill ruins and I think we had a couple of brief photo stops too. We had a really funny guide on that tour. The "St. Thomas Island" tour stopped at a couple of places too...one was a shopping stop.
This year we're going to try the Rhino Rider in St. Maartin and I'm not sure what we're going to do in St. Thomas.
Hope you have fun!!
