Is it best to bring lots of pesos with us. Myself and three girlfriends are coming at the end of the month for three weeks. I have been before and loved it but none of the other girls have. They are a little nervous. I used the bank machines last winter but noticed the exchange could get a little pricey and varied whereever you went. Our hotel wants us to pay upfront in pesos so that is quite a lot of pesos to carry. Is it cheaper/easier to just buy those at the airport before we get on the bus? Or should we bring sufficient funds with us to pay for the hotel and get a few things in to our spot before venturing to the markets etc.
