Cozumel is way less expensive. But there is probably more to do in the Mayan Riviera. Actually, screw those resorts. I would like to hit somewhere not so touristy and off the beaten path like PUERTO ESCONDIDO. Would like to be able to walk up to a fisherman and strike a deal on some fresh fish or oysters, lobsters, or and have a good cook fix it up for me and the old lady. And a case of cold brews of course. Coconut for the lady.
