We're going as a family of 4 (two boys aged 7 and 11) on our first Disney Cruise this February, 2013 (first cruise in general for the kids) and we're looking at different ideas for the off shore excursions. The two stops on our 5 day cruise are Cozumel, Mexico and Grand Cayman. We're thinking for the Cozumel stop about either the "Fury Catamaran Sail Snorkel and Beach Party" or "The Secret River and Playa Del Carmen" excursions. For the Grand Cayman off shores we're thinking of either the "Island Tour and Snorkeling with Stingrays" or the "Rum Point Beach Adventure and Stingray City Snorkel". Has anyone been to any of these excursions? what were your experiences? would you recommend one over another? were there any other excursions that you've done that you would recommend? on that note, are there any details that we need to be aware of or watch out for in either/both locations? Thanks so much in advance for any and all feedback.
