I'm going to the western carribean on March 7th on the Grand Princess. I'm trying to figure which excursions to go on. Our stops are; Princess Cays , Costa Maya, Grand Cayman and Cozumel. I enjoy snorkeling and sunbathing and few cocktails. I don't think I would enjoy sightseeing at some of the ruins. I know we'll check out the stingrays. Does anyone have any suggestions?
