Make several copies of your passport, tourist card, and airline tickets. Whether you’re traveling solo or with others, leave a copy with someone you trust at home. Store one copy in a separate bag and if you have a travel companion, give a copy to him or her. Be sure to carry a copy of your passport and tourist card in your purse or wallet and leave the originals in the hotel safe or locked in your bag; they’re a lot more likely to be lost or stolen on the street than taken by hotel staff.
When you move from place to place, carry your passport and important documents in a travel pouch, always under your clothing. Write down your credit card and ATM numbers and the 24-hour service numbers and keep those in a safe place.
