GSW. We were in St, Maartin last December and went to Dawn Beach for the day. It was VERY rough on that side of the island that day, so snorlelling was out of the question (I did try, and didn't see much in the way of a reef). I rented a boogie board from the stand that rents chairs, etc. and had a BLAST! They have two little outdoor snack shops/bars right on the beach. The beach itself is very clean St. Maartin itself is very easy to get around. The pier has signs everywhere telling you which taxi, etc. to get on. Hope this helps.
