Look into paying in your local currency when traveling internationally

Check if your hotel/restaurant in a foreign country will charge you in local currency or your country of origin's currency. Also, be aware of what is the going exchange rate as this will determine what to do. For example, usually your bank will charge you a foreign fee for the transaction if it is done in the local currency, but if done in USD there is not charge. So if the exchange rate being used is less than the exchange rate plus the foreign fee your bank charges then it is a good deal.

It sounds complicated, but if you spend a lot abroad, it may be worth it to pay attention and make the right decision.
