Thank you Nancy and Sunprincess for responding.
Nancy you have helped my family so much on two of our excursions and this is the last one I need to schedule. If you could help (or anyone else)..... We have decided to try and book with Buccaneer in Grand Cayman. The departure time is 10:30 am and the arrival time to the dock is 1:45 pm. Do you think we have time to do this excursion on our own if the ship (Royal Caribbean) arrives at 7:00 am and departs at 4:00 pm? Buccaneer stops will include Coral Gardens, one other snorkeling place, and the stringray city. Have you ever snorkeled at the Coral Gardens? Do think the kids will see much fish?
