October 2016, MEXICO CITY — The place to buy bus tickets has changed. It is no longer next to the McDonald’s across the zocalo. It is here, a few store fronts down the row:
This is a little ticket stand selling ADO bus tickets on the same stretch of shops lining the street opposite the zocalo, but it’s hard to find. The stand is in the Way Back. Only open 10 a.m. to 5 p.m., Monday through Friday. One person and a computer. Cash only.
Another Option to Buy Bus Tickets in El Centro, CDMX
Travel agency at Hotel Rioja, Av. 5 de Mayo 45, Centro, 06000 Ciudad de México, D.F., Mexico, Tel: +52 55 5521 8333. The travel agent is there from 10 a.m. to 6 p.m. and can book on any Mexican bus line. Cash or Mexican credit card.
We used this option to buy our tickets on ADO to Cuetzalan del Progreso the day before we were set to leave. We had to pay first, then return to get the tickets. It seems they were printed/issued in another site.
Hope this helps with your travel plans!
