I did several years ago. If you have never done a sting ray adventure its kool. The Ray's at the Cococay location are in a fenced in area, I believe for patrons protection as at Bahamas are known to be a shark area ( we did see a small one outside the fenced area. The sting ray excursion in Grand Cayman out of this world!! out in the ocean, on a reef, hundreds of them swimming around you. Both locations you hold, feed and pet the rays... it is an amazing experience!!
