Pesos To Dollars And Other Currencies

People coming on vacation to Mexico ask what type of currency is best to have for spending. Can you use US Dollars in Mexico? Do I need to exchange money? Is it better to use Pesos or Dollars in Mexico?

I found this on the web and I've used it for all of my international travel.

US dollars may be used throughout Playa del Carmen but the exchange rate will be very poor. The locals are very aware of the exchange rate and are good at this game. The best place to use your credit card is at the large supermarkets. Chedraui, Walmart, and Soriana will give you the best exchange rate.
