We are a group of friends, speak Spanish fluently, and are going to be in Mexico for a week in November. The plan is to arrive, spend 3 nights at an AI in cancun, take the rental car to Valladolid and stay the night. I figure we will be on the road at noon, and there around 2pm. Check into a hotel and go visit Ek Balam and maybe try to swim in the cenote in town (anyone know the hours?). Next morning do Chichen Itza and hit some cenotes on our way to playa del Carmen where we will be renting an apartment for another 3 days. Is that too ambitious? Should we just check out Valladolid rather than do ek balam? Any suggestions would be welcome. Also, how much do guides cost at each?
We were in PDC last year and did Coba and cenotes and had a blast.
