Tourists from Europe would be wise to check with Dominican sources prior to arriving with their euros, as it is likely to be more advantageous to exchange their euros at home, carrying with them US dollars for their travel to the DR. Today, the Central Bank posted a buy-rate of RD$39.38 to US$1, but the spread for buying euros is significant. While the official rate is RD$40.61 to one to buy euros, the sell-rate is RD$46.08.
