I saw this article on an Australian news site and it got me thinking... http://www.news.com.au/travel/trave...g/news-story/4d63c7f689222eeb51628ff6a0434070 Have you learned from any travel you've done, where you've spent more than you should? Do you have any lessons for the rest of us that might save us some money? I have done last minute cash exchanges at the airport before (like they mention in the article!) and they definitely charge a premium for it - it would have been way cheaper for me to do it at my bank before heading overseas. Also, withdrawing cash from international ATMs can be so expensive, they often charge an international withdrawal fee - so I try only to withdraw cash if it's absolutely necessary.
