Money, Money, Moneyyy! The number ONE most important thing to do is to let your bank know when and where you’re traveling. Nothing sucks more than your bank putting a hold on your card. With that being said, I also suggest taking the money you have for your trip and splitting it into two separate bank accounts. This way if one bank puts a hold on your card, or someone steals one of your cards, or whatever reason, you’ll have some money to get you through until you can sort out whatever needs to be done. My last tip is to try to skip the currency exchanges, they’re a business who needs to make money and how they do this is by taking a hefty percentage of YOUR money. So stick to the ATMS if you need cash.
