I decided to go for the following route now:
Most probably Playa del Carmen from 12th to 16th and try my luck there, even if the gringo bonus isn't existant here anymore. At least chicks have time here because they are on vacation, unlike in CDMX for example. Merida would be the other option. Apart from chicks PDC might be more enjoyable though.
Then 16th to 25th rent a car with my home town girl and go to Valladolid, Chichen Itza, Tulum and Cozumel.
26th fly to CDMX and fly home.
