We took the Island Tour & Snorkeling with the Stingrays. It was EXCELLENT. I'll have more details in my trip report (when I finally get around to writing it), but we visited the Turtle Farm, Hell, and then Stingray City.
The water was a little cool, but you get used to it. The guide caught one of the Stingrays and let us hold it for pictures. They pretty much just swim around you, bumping into you occassionally (many screams were heard when this happens). The only things you have to be careful about is not stepping on them and feeding them properly if you choose to do so (otherwise they will bite - just hurts a bit, but doesn't break the skin). DW just stood there a watched while snorkeling and I fed them a bit.
It was a GREAT experience and the shore excursion is one I would DEFINATELY do again.
