My 12 year old daughter and I will be on our 4th Disney cruise in December. It will be our 4th time visiting Castaway Cay. We have done the bike riding, Castaway Rays stingrays, snorkeling at the family beach, and parasailing. Any other suggestions for what we might do at Castaway Cay during our next cruise? I was looking at booking the Rigid Hull Snorkeling Excursion. Anyone done that or have other suggestions? Thanks
