I have not done this tour, but wanted to comment due to the weather on Nassau. Salt Cay did have a Swim with the Sting Ray tour. Nassau is in the Bahamas' and therefore the water is not as warm as in the deeper Caribbean. If you are cruising within the next two months, January or February, the water may be pretty cool. You could have a beautiful 70 degree day with lots of sunshine or it could be cool and breezy. Just a heads up. If you don't do this tour, take a taxi to Atlantis Resort and explore their property and take a tour of the Dig. It is really amazing.
