Is it best to change money at the airport?
This is fine for convenience only–to pay for your airport taxi and your first transactions. Otherwise, if you must exchange money, head to one of the main banks in the Dominican Republic–they use the Central Bank’s daily rate as the benchmark for exchange transactions, so the difference in the exchange rate between banks is negligible. Banks close at 5pm on weekdays, but most branches inside shopping malls remain open until around 7pm-8pm. ATM machines are available at supermarkets and shopping malls until later hours. For security reasons, it is best to use the exchange services or withdraw from ATMs as you go along.
