For travel within the Zona Hotelera, buses R1, R2, R15, and R27 stop every five minutes along Boulevard Kukulcán and cost a flat MX$10 no matter where you get on or off. The R2 and R15 continue to El Centro’s Wal-Mart and Mercado Veintiocho; the R1 goes as far as Puerto Juarez and the main bus terminal in El Centro.
Buses for farther-flung destinations leave from El Centro's terminal. One of the oldest bus lines in Mexico, ADO has first-class buses that stop incrementally at Puerto Morelos, Playa del Carmen, Tulum, Felipe Carrillo Puerto, Limones, and Chetumal; the full trip (concluding in Chetumal) takes 5 hours and 45 minutes and costs MX$354. Fifteen buses make the trip daily, departing between 6 am and midnight. Mayab, a division of ADO, has second-class buses leaving for destinations along the Riviera Maya every hour.
