Probably too late, but pretty much everyone I know takes plastic abroad.
If your credit/ debit card charges, then get a prepay. You will always get a better rate of exchange withdrawing from an ATM in your country of destination than you will in changing money. Well, I admit my knowledge is based on UK/ European banks
I used ATMs in Amsterdam because many, many places don't take plastic there - odd in a capital city but perhaps because fraud has been a big problem. But at the time there was a zero charge for using LINK cards anywhere. Since the banking crisis I believe this has changed. In fact British banks are now even floating the idea of charging for current accounts. So I'll be withdrawing my wages in full once a month and putting them under my mattress...
More pictures. Moar, moar, moar.
Toilets and food and landmarks and family mugging for the camera and a travelogue when you get back please. Never been to Canada and would like your take on it as a furriner but neighbour.
