money exchange

Will we be able to exchange $$ at the airport on saturday afternoon or are they closed on weekends like banks?

We were at Velas Vallarta in November 2002 and received the best rate at the hotel. Can also exchange in town or use your debit card.
You can also use your credit card but beware 3 years ago we were ripped off for $5000 canadian dollars as were the two couples travelling with us. Our credit card company reversed the charges but it makes you cautious.

We got back on the 14th of Jan and the best rates we found were 10.25 on the US dollar and 6.45 on the CDN dollar. This was at a cambio (money exchange) downtown.
