Your Security is utmost important when traveling alone especially for women and children. When going through metal detectors at airports, do not put your laptop on the conveyer belt immediately, wait until there is no one in front of you. there have been scams where you put your lap to on the conveyer belt and the person in-front of you has a metal object on them causing a delay for you and other behind you while his accomplice at the other side whisks you laptop away. Also when on vacation don't let you brain go to sleep. You may in a beautiful area but sometimes evil minded people are looking for vulnerable people to steal from.

Leaving cameras and valuables in plain sight is not a good idea. Also do ot carry cameras and other equipment in branded bags, try to conceal such items in a regular backpack or in any other less obvious way.

While in big cities try to keep your windows up and doors locked, and valuables out of sight. Travel on well lit, busy routes.

When checking into a hotel never take a room whose number has been announced out loud. Make the clerk at the desk write it down.

In conservative countries do as the natives do wear a veil if the women do. It will protect you from the sun and from unwanted attention. You do not need to be concerned how you look like ( so what if you are having a bad hair day) and it shows respect for the culture.

Enjoy your travel
