dear soccergirl, i swam with the sting rays at grand cayman last year. i went alone as the rest of the family wimped out. it was an interesting experience but i probably would not do it again. it took over an hour to get to sting ray city, which is the sand bar where the sting rays congregate. the trip includes a walk from the ship to a bus, bus to a boat and then a boat ride to the sand bar. it is not a reef so except for the sting rays and the water there is not much to see. in addtion, you are with over 100 other passengers some of whom scream every time a sting ray brushes by.
