I would guess that the difference is that the tour I booked adds a stop at the barrier reef (which I wasn't that excited about, but it was the only tour I could find available that goes to Rum Point), and includes lunch.

We did the Discover Cayman tour just a few weeks ago on the Conquest. It was wonderful! It was the only one of our excursions that we booked thru Carnival, at the other ports, I had pre-booked online on my own.

The Discover Cayman Tour is done thru Kelly Tours, which is a family-owned operation. Our guides were wonderful, knowledgable and extremely friendly. Our guide KNEW those stingrays, and even had names for them. He explained that his family had been going out to the Sandbar for many years.I would book the exact same tour again if we go back to Grand Cayman.
