Currency - Mexican Peso
The Mexican Peso is the national currency.
In general, you can use pesos, US dollars and travelers checks easily in the Riviera Maya Coastline of Mexico.
We would not recommend exchanging your money in the airport upon arrival. They typically do not have a very good exchange rate. You would be better to exchange once you have reached your destination. You can compare exchange rates at local banks vs the local exchange places (Casas de Cambio).
In the Riviera Maya, we have not found a business yet that would not except American Dollars for payment. The only downfall to using American dollars is that you will never get as good of an exchange rate but it is possible and accepted.
We also have found that Travelers checks are widely excepted as well.
Do not expect to be able to use your credit card everywhere. Many Many places do not accept credit cards in the Riviera Maya area.
