Hi Penny - I think we've emailed before. Our favorite thing to do in Cayman is to walk the 7 mile beach (stopping for an occasional swim - the water is wonderful) and have lunch at one of the hotels on the beach. It's really only 4 miles long. We;'ve been there twice. Once with RSSC and we did go to StingRay City/Hell/Turtle Farm. We did not snorkel there, but, RSSC did have a snorkel tour with the StingRay City excursion. We went in a viewing submarine while a diver fed the stingrays. It was interesting, but, we preferred the walk/swim/lunch.
