Hotels at the Mexico City Airport

If both your flights are in the same terminal, stay at a hotel in the terminal.
If your first flight come into terminal1 and your 2nd flight is in terminal2….I would stay in terminal 2 and the NHHotel.
If your first flight come into terminal 2 and your 2nd flight is in terminal 1…I would stay at the Camino Real at terminal1.
Enjoy your vacation.
