In Key West it was cool to take the trolley tour, in Grand Cayman we've done the sea turtle farm, that was cool, also the submarine was very cool, and swimming w/ stingrays!! that is pretty neat too! In Cozumel, we've done the snorkeling. that was beautiful!!! also swimming w/ the dolphins!! they were all amazing and would do them again in a heartbeat!! i think most of 7 mile beach is pretty much private... but beautiful... if they have an excursion for that , it would be fun, but I forget if they offer any. I have always done all my excursions through Disney...
