Bull, another cool thing to consider is pre-paid VISA cards. I am not a big fan of coming home from vacation to face credit card bills, so I have been using VISA Pay Power on my last few international trips.

There is a small activation fee ($3.95 to $5.95), load up the card in advance with the sum of your choosing and off you go! Just make sure you get a card that does not say "for use in the U.S. only".

You can set up an account on your home computer in 5 minutes. I synch mine to my iPhone and I can find out my balance whenever I want. No transaction fees, just the initial activation fee. Plus, you can re-load for your next adventure!
