Hi Tanna. That could work. I have to coordinate with the family, so either I would come out early by myself and then head back to get some snorkeling in with them, or if not too early of a start, they could come along and they would snorkel at the dive site or nearby, or do other stuff in town. Depends on when the water gets rough, and if you tyically do one tank or two. I sure like the idea of getting some local knowlege. Let me know your thoughts.
