Buses:

One of the best values in Cancun are the 3 private bus lines that that go to and from the hotel zone to downtown/centro Cancun. The one way fare in the hotel zone is $8.5-Pesos. There are now newer and air conditioned buses. All bus route numbers are displayed on the front windshield. The main routes are the R-1 and R-2. These buses run 24/7. For those wanting to visit downtown's large Plaza las Americas take the R-27 Bus. This bus does not run 24/7 and during the day runs about every 20 minutes. It will leave you off right across the street (Avenue Tulum) from the plaza. You will get off the bus in front of Sports City. There is no foot bridge so you have to be careful crossing Avenue Tulum or walk back 2 bocks to the corner. The R-2 Bus is best for going to:Walmart (open 24/7) Sam's Club, Market/Mercado 28 and the Hong Kong Restaurant. Most drivers will say when they get to this stop. The R-1 Bus turns right on Avenue Tulum goes past city hall and is where you can get off for the city's main bus terminal (just past the Uxmal Avenue Traffic Circle). The terminal will be directly across Avenue Tulum.  Most city buses go out to regions where many locals live. The fares are one way so if you want to go to the end of the line you will have to pay another $8.5 Pesos to return back to the hotel zone. The morning rush hour going into the hotel zone runs from about 6:30-AM to 9:00-AM. Many buses can get very crowded. In the afternoon the rush hour heading to downtown runs from about 4:30-PM to 7:00-PM.

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 air conditioned.  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.
