So I am planning a two month ish trip to Mexico and Guatemala. I have booked my flight to arrive in Mexico beginning of October, I want to be in Oaxaca on the 31st of October for the beginning of Dia de los Muertos period. However I was planning to fly direct from Mexico to Guatemala first maybe just spending one day in CDMX when I arrive and then onto Guatemala for 2/3 weeks. If I went this way what’s the best route back to Oaxaca to arrive on 31st and continue my travels in Mexico. Or is there a better solution to organising this trip better? Thanks for advice in advance.
