Excellent
We had our bus transfer pick us up from TUI BLUE El Dorado Seaside Suites, was quite a long way to Cancun but was all absolutely fine. Once our guide arrived we were able to leave our belongings in lockers (free of charge), and carry on. We followed our guide in our 2-man speedboat (my wife piloted first, I piloted the way back). We snorkelled at the halfway stop at the coral reef, checking out the tropical fish, and it was a perfect trip. And our guide was great too, we felt in safe hands.
