Exchanging money is a very popular topic because everyone wants to know how to get the best deal on exchange for their dollar or whatever currency you are exchanging when you come to Playa Del Carmen. Bottom line is, don't sweat it. Second, don't exchange before you get here.
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?
