OK, I'm squeamish over the idea to begin with...swimming with stringrays. We're from Michigan...there are a few minnows around your ankles when you get in the lake and they scatter quickly. NO experience with marine life here!!! But, I'd like to plan something cool for my pre-teen/teenage kids. Assuming I get over the creeepy feeling, what about the water level? I've read it could be as high as 6 feet, which would be over all our heads. And if not Stingray City, does anyone have "can't miss" excursions for Grand Cayman?
