Exchange money
                             

It is important to exchange some money before you leave for your trip. You’ll probably encounter the advice that it’s better to exchange currency in the country you’re traveling to and that’s usually true. However, you will want to have some cash prepared for when you arrive. There is going to be some amount of travel time, between landing in your destination and getting the chance to exchange more money, where lots of things can go wrong. It’s a good idea to have a little cash on hand, including small bills and coins if possible, so that you’re prepared for anything.
