This trip allowed me and my teenaged son to easily combine 2 activities we were trying to squeeze into a family schedule. Gorgeous scenery, terrific snorkeling spots (we saw 3 turtles and a hundred or so fish). Also, our guide (Mark) gave us some interesting history and background information about the islands, the reef, the ocean, etc. but didn't talk just to talk, as tour guides often do--again, a perfect balance.
