We did the coral land and coral sea tour. The semi submersible boat was very neat for viewing the reef inside the bay, but it was very short and coral world is ok but nothing special. Would not do this again.
St Maarten was beautiful. We spent the day shopping and walking around Phillipsburg. I hate shopping for the most part, but the local people were so friendly and just about every store we went in they would give us free alcohol of some sort. Thats my kind of shopping and prices were great on most everything we looked at.
