i'm going to xcaret from hotel zone. i've read you can get there on taxi, ado bus, mayab bus or with included transportation (tour xcaret). im looking for the CHEAPEST option. taxi definitely the most expensive, then tour xcaret, then ado and mayab bus (colectivos only run from playa del carmen, not from hotel zone, right?)
however, i've checked in ado's page and the saving is minimal. i've read mayab is cheaper but i can't find info on where to take it, where to buy the tickets, prices and what is the schedule.
