My partner and I are traveling to Bali in sept, first time overseas so we r clueless! Question is now the Aussie dollar is dropping are we better off buying some IDR before we leave while it's still at a half decent rate? If yes is it better to buy cash or travelers cheque or some type of card? We were quoted us dollars for our accommodation but I'm assuming we should pay in IDR? Thanks in advance for your patience guys!
