Here's an interesting travel tip:
If you leave your valuables [passports, jewelry, money] in your hotel safe, leave one of your shoes with it in the safe. When you pack up, a missing shoe will remind you that you have your valuables in the safe.
Also, xerox your credit cards and passports. I leave some of my credit cards in safe, and carry the others with me for purchases. We also carry the photo of the passport with us if we need it for detaxe purchases.
