The US dollar is as widely used as the franc, but watch the rate. It is sometimes difficult to get change from payments in francs.
Dollars are preferred.
The best place for exchange is the post office in Marigot where they will change all currencies and travellers cheques, but normally only into francs. There are several exchange houses for changing from francs to dollars, one in rue du Kennedy and one in the Marina Royale complex. Two banks, both on rue de la R publique, Marigot, Banque des Antilles Fran aises and Banque Fran aise Commerciale. All rights reserved.
