Just a tip if you haven't used your credit card out of the country before: With the current credit crisis, most card issuers have tightened up on policies and restrictions. Depending on your bank, they may "red flag" your card when you try to use it out of the US, which means they cut you off cold and you have to waste your time and $$ on the phone trying to prove that you are actually the one using it and not someone who stole your number. This can also happen when the card doesn't go through the first time they swipe it, and then they swipe it again- also a flag- and you should never let them swipe it twice unless you want a lot of hassle.
SO, IF you decide to bring your credit card, be sure to call your credit card company and LET THEM KNOW that you will be out of the country for X amount of days. You may also want to lower/raise your daily limits at this time depending on your needs.
Have a great trip, and I totally agree with Captain Oil!
