I go from time to time, last trip was St Martin, St. Barth's and Anguilla, also been to and USVI and BVI many times as well as Aruba and Barbados.
They're all too built up. Even Anguilla (which is the trendy one now, Jessica Simpson was there while I was I think, apparently it is "hot" now) is getting overdeveloped - they are putting in an 18 hole golf course and a runway for jets; I had to go by boat.
Aruba has a friggin Old Navy on it. St. Martin has a Church's Chicken.
I just don't like the island life. I get bored pretty fast. Another issue is that except for the nicer (tourist) areas, the islands are practically Africa-poor.
I actually decided to take a break from Caribbean trips for a while. That may be more reason for you to go, lol.
