My husband and I and our four kids ages 13-19 will be sailing on Mariner the first week of May. We will be on the beach at Coco Cay and St. Thomas, but we aren't sure what to do on St. Maarten. We don't mind more beach (we're from Idaho and never get enough!) but I don't want to take teens to a nude beach. We don't care much for shopping, and we do plenty of hiking/ATVing at home. Any ideas?
