From what I remember, the stingray enclosure on CC isn't that big. You first do the encounter(feeding, etc.) and then you have time to snorkel with the stingrays in a roped off area. IMO, snorkeling with the stingrays is much like snorkeling at the family beach--you decide how far out you go. For most of the stingray area, the water isn't that deep(I'm 5'4'' and I could stand on the bottom without the water reaching my neck in most of the stingray area). The stingrays mostly swim around you and you can just watch them if you prefer(I did both).
