Can anyone give me a general idea of what the current exchange rate is for US dollars to pesos? I know it varies from place to place, ATM to ATM. I was quoted 12.70 pesos per $1 US and trying to determine if I should exchange here or wait until I arrive in Cancun. I usually use an ATM at Walmart in el centro but won't be able to get there until 4 days after my arrival in the hotel zone. Thanks!!
