The currency used in Lake Buena Vista and across America is the U.S. Dollar. You’ll be able to find numerous ATM machines and foreign exchange facilities around the resort. We suggest that you buy your travel money before you leave the UK. You can buy Dollars online or from any Thomas Cook store. Find your nearest store here. Both ways are much cheaper than buying it at the airport. If you’re not sure how much money you want to take away with you, then why not check out the Thomas Cook Cash Passport?
