hi there,
US dollars and Euros are the most easily exchangeable foreign currency into the local Dominican currency, the Dominican Pesos (RD).
Exchange money in banks and independent money exchanges rather than airports, hotels/resorts, restaurants,as they offer a slightly lower rate of exchange.
In a lot of the tourism destinations in the country, many of the hotels, restaurants and businesses indicate their prices in US dollars as well as in Dominican Pesos, and would actually prefer to be paid in US dollars.
Major credit cards and traveler's checks are accepted at most of the larger hotels and
resorts but the surcharge can be a bit too high!
In the larger resort areas/towns/cities you will find banks that also have
cash points which are accessible 24 hours per day.
Hope this helps
