If you're on the Dutch side, they have always charged me exclusively in Dollars, so it shouldn't be an issue. On the French side, you may have to engage in some mental gymnastics if you're so inclined, and compare their exchange rate differential to the 3% vigorish to determine the better way to charge. But, some places only charge in Euros. Also, some places offer a better exchange rate for cash $, so you might want to use cash in places that offer favorable exchange rates for cash.

And, I am aware that many folks don't want to engage in these mental exercises during vacation.
