We just got back from St. Martin, today. Took a one tank afternoon dive with Scuba Fun, located right near the Cruise dock next to Chesterfields restaurant. They were very nice and professional. Laney was the DM and she was great. My son hadn't been diving in several years so we just did the one tank shallow dive in Little Bay. There two tank dives sounded more interesting but we didn't really go there to dive, so this was fine.
