How much is the shuttle to the Occidental? From the airport to Blue Angel recently was only US$11 per person, which is not enough of a hit to warrant going to the airport ATM to get pesos in addition to the rest of the task loading associated with arriving in Cozumel.
We go there often (as you do too) and we always bring home pesos so that we have enough for a day or two next time we arrive. We just came back a few days with 2500 pesos, about $150, which will cover our shuttle and a couple restaurant meals next time we go. Takes away the urgency to find an ATM.
