Just a quick question. Our hotel site quotes a price in US dollars but says that you pay in Rupiah on check out. Would it make sense to buy US dollars now to that amount and hold them until our holiday then change to rupiah in Bali or just change Aus dollars over there at the time? Cant get my head around all these different rates. Am thinking that if we buy US dollars now at least we know we have the money to check out with.
