Has anyone every been to Costa Maya, Mexico and if so, is it worth it? I am looking at two sailings, one on Royal Caribbean and one on Carnival, for a group cruise. The one on Royal Caribbean goes to Costa Maya where the one on Carnival goes to Grand Cayman. Both itineraries include Cozumel. I am basically trying to build a group cruise that is essentially a sampler of what cruising can be, an introduction for newbies and a chance for veterans to share their experience with the newbies. This includes adventure cruising, ecotourism cruising, beaches, and shopping of course. A bit of a Caribbean Highlights thing. If anyone can advise me on these two ports of call, please feel free.
