Hi RAJohns, welcome to Cruise-Chat. Thank you for letting us know about your experience with this excursion. Sorry to hear it wasn't what it was advertised to be. I do hope the excursion desk listened to you and investigated the tour operator(s). We have been on a few excursions that upon returning to the island were no longer offered due to bad reviews from the passengers. One of them was a snorkeling trip where the captain drank to/from/during the excursion. The snorkeling was fantastic, so it was sad to lose that, but we were glad the operator was no longer used by the cruise line.
Glad to hear the rest of the cruise was great and your other excursions were worth the money. Best wishes!
