It's coming up on my 04/06 cruise date. I'm going to visit 2 beaches in St. Thomas and Castaway Cay will also be a "beach day". I'd rather not do a 3rd day of beaches in St. Marteen. Shopping seems like it's good in St. Marteen but I can envision shopping "all" day there. So other than shopping and not wanting to do beach stuff...any other suggestions? Thx.
