I will have a two hour stopover at Changi Airport on my way home to Australia, at the end of May. I will have Euros and Australian dollars with me. Is either currency accepted at this airport or should I change some into Singapore dollars? If so which? As I am on my way home from Paris, I will probably only buy small toys for my grandchildren as space, weight and money will be prohibitive. I will probably visit Singapore again well before I visit Europe. However I am hopeful of getting to the US in the next year or so, should I change all the Euros to USD and hang on to them? I do hope some seasoned traveller with some knowledge of currency and its intricacies will have some advice for me.
