For a long overnight route like this, treat any fare or timetable shown here as a current snapshot rather than a fixed schedule.
Departure in Cancún
Current direct listings use ADO Terminal, Cancún Centro. This is in central Cancún, not Cancún International Airport and not the Hotel Zone.
Check the terminal printed on your ticket before leaving for the station.
Arrival in San Cristóbal
Booking platforms do not currently label the San Cristóbal arrival point consistently. CheckMyBus shows Portal Oriente on several current searches, while Busbud uses the generic San Cristobal de las Casas stop label.
Because those labels do not fully agree, use the exact arrival point on your ticket rather than assuming a specific terminal.
