In this Post I am going to share with you some advice that I read on many web sites a bout the trips, how to make it easier and safer. Some times a silly mistake can make our nice journey very bad, and we wouldn't do it again.

Here are some advice about what you should do Before you go, and I hope later I can collect more and post them here.

Safety begins when you pack. To help avoid becoming a target, do not dress in a way that could mark you as an affluent tourist. Expensive-looking jewelry, for instance, can draw the wrong attention.

Always try to travel light. You can move more quickly and will be more likely to have a free hand. You will also be less tired and less likely to set your luggage down, leaving it unattended.

Carry the minimum number of valuables, and plan places to conceal them. Your passport, cash and credit cards are most secure when locked in a hotel safe. When you have to carry them on your person, you may wish to put them each in a different place rather than all in one wallet or pouch. Avoid handbags, fanny packs and outside pockets that are easy targets for thieves. Inside pockets and a sturdy shoulder bag with the strap worn across your chest are somewhat safer. One of the safest places to carry valuables is in a pouch or money belt worn under your clothing.

If you wear glasses, pack an extra pair. Pack them and any medicines you need in your carry-on luggage.

To avoid problems when passing through customs, keep medicines in their original, labeled containers. Bring copies of your prescriptions and the generic names for the drugs. If a medication is unusual or contains narcotics, carry a letter from your doctor attesting to your need to take the drug. If you have any doubt about the legality of carrying a certain drug into a country, consult the embassy or consulate of that country before you travel.

Bring travelers’ checks and one or two major credit cards instead of cash.

Pack an extra set of passport photos along with a photocopy of your passport’s information page to make replacement of your passport easier in the event it is lost or stolen.

Put your name, address and telephone numbers inside and outside of each piece of luggage. Use covered luggage tags to avoid casual observation of your identity or nationality. If possible, lock your luggage.
