Buses:
It's convenient and very inexpensive, about U.S. $0.70 per trip to get around Cancun by bus. Buses are frequent and come every few minutes. City buses travel up and down the Hotel Zone and into Downtown Cancun and the station there. Not all city buses are airconditioned. Driver will make change if you use pesos but USD are accepted.
ADO BUS
First class buses that travel to Playa del Carmen then on to Tulum and to the Cancun Airport are direct with A/C and often show a movie on board. Mayab buses are second class that make stops along the route and travel to many points in the area. Tickets may be purchased 24 hours in advance and luggage is stored underneath.
White vans provide transportation up to Puerto Juarez to the ferry to Isla Mujeres and run all along HWY 307 from Cancun to Tulum. Drivers will drop off and pick up passengers at any point along the highway providing transportation to day excursions like Xel Ha , Xcaret, Akumal, Rancho Baaxal, Tulum Mayan site and Playa del Carmen.
