TIP CORNER
Flight
An item that's invaluable when making long, night flights is an inflatable neck cushion (pillow). It takes practically no room when collapsed, but makes it so much easier to sleep
Foreign Hotels
When leaving the hotel, always take matches or stationery with hotel name and address on it. When you don't speak the language, just show the cab driver either one and there won't be any mistake as to where you are staying.
Valuables
Have a photo copy made of your passport ID page, airline tickets and credit cards before you embark on your trip. Keep them somewhere other than with the passport and tickets. If you lose any of the above mentioned, the photocopy will expedite getting replacements.Always carry extra passport photos. Handy if you need visa in a hurry, or if you lose your passport
Health/Water
If the water is not drinkable, then remember the ice probably isn't either, so do not drink anything containing ice. By the same token, reconstituted fruit juice should not be drunk.
Jet Lag
Try to go to bed a little earlier a few days before you leave and get as much sleep as you can during your flight.
Exercising on a long flight will help alleviate such common discomforts as backaches, swollen legs and feet and general fatigue. Stretch at regular intervals and walk up and down the aisles of the plane from time to time
Money
Always exchange a small amount of currency before you leave to pay for taxi if needed at your destination.
I find that using a credit card is the best way in most countries. The rate of exchange is far better than you could get for either cash or travelers checks and the fees charged are considerably less.
If two of you traveling together, each one carry a different credit card. If one is stolen or lost, you'll still have a valid one. Also, if magnetic stripe goes bad, you still have the other one to use.
Packing
If you are traveling with someone, pack half your clothes in his bag, and carry half his in your luggage. Then if one bag gets lost, you at least have half your things.
