Cancun, or, more precisely, Cancún, is a coastal tourist city on the Caribbean (eastern) side of Mexico. There are two significant areas, Punta Cancun (tip of Cancun), also known as the Hotel Zone and Playa Del Carmen. We chose to stay in Punta Cancun. The Hotel Zone is walkable and you don’t need to rent a car if you are staying there. Buses are always available to go to other parts of Cancun though you rarely will.
