Ultimate Snorkeling Adventure

Has anyone been on Carnival's Ultimate Snorkeling Adventure in Grand Turk? I have heard of an excursion that takes you to the drop off and wanted to know if this one does. Thanks

When we were in Grand Turk last month, we did a three-stop snorkeling tour with Blue Water Divers. There were only four of us [we got our group together via our Roll Call, as BWD wanted at least four]. It was outstanding! $50 each, very easy to do. Grabbed a cab up there and the young man driving our boat left us off at the beach at Jack's Shack. We walked back to the ship along the beach. One of our stops was "the Wall" - amazing!!
