A friend of mine will be joining Claudia and I on our visit to Merida and Cozumel next week. The plan is she takes the ADO bus from the Cancun airport to downtown Cancun, then the ADO bus from Cancun to Merida to meet up with us. Two questions:
1. are there ATM's in the Cancun airport (terminal 3) where she can get pesos for the bus?
2. does the airport to downtown bus take US dollars?
3. does the ADO station in downtown Cancun take US credit cards for fares to Merida?
4. are there ATM's at the downtown Cancun ADO station where she can get pesos?
