Royal Caribbean the best???

Lots of changes to Cozumel since hurricane Wilma, but very much for the better. Every one needs to understand the beaches in CZ are not great, limestone rock in most places, some sand. Skip Playa Mia beach, everyone is there, watch for scams, they will try to sell you pawnshop jewelry/watches. Take the ferry to Playa del Carmen and enjoy the beaches there, they are awesome. Check excursions offered in the area by other providers, not just the ship. Some are so much better than these offered and can be done with enough time to shop and return to the ship.
