Pay for the "Big" stuff with T-checks or plastic, but have lotsa small U.S. bills for daily survival...like breakfast and beer. Use 5's 10's and occasionally 20's...Try to pay as close to the amount as you can, they will usually give you change in Bze. You'll end up with 25# of Queen Liz's portraits. Can be a long wait if you try to exchange at the airport when you depart.
