The real working city inland from the beaches, with markets, taquerías and far cheaper hotels. You trade beachfront for value and a more local feel; frequent buses run to the Hotel Zone in about 20–30 minutes.

A small, relaxed island a short ferry from Cancun, with the calm, shallow Playa Norte and golf-cart-sized streets. A quieter, more low-key alternative for those who want the Caribbean without the resort-strip intensity.
