We've been coming to the French side for over 20 years and always used dollars without a problem.

Make sure your credit card doesn't charge international fees.

Check your credit card Euro exchange rate just before you come.

Whether you use cash or credit card is a personal choice. But remember to ask restaurants and stores what their exchange rate is for dollars before you pay in dollars. (We usually pay cash, but will use our credit cards if we aren't being offered a good exchange rate for cash.)

Have a great trip.
