For the first time in years, the dollar is now king, especially against the euro, which has fallen about 30 percent in value.

This is great news if you’re traveling abroad. The U.S. dollar has had the fastest rise against some foreign currencies in 40 years.

So how do you deal with currency? Many of you opt for the convenience of changing your dollars into euros before you leave home. That’s a mistake.

You’ll get a terrible exchange rate, and then there are commissions, on both ends of the transaction—when you change your money, and when you change it back.

Use your ATM card when you get there. When you pay for something overseas, you’ll be asked to pay in euros or dollars on your credit card. Don’t pick dollars.

Always pick the currency of the country you’re visiting. This avoids a markup in the currency conversion rate.
