Fire: When you first go into your hotel room, take a moment to look back out into the corridor and note where the fire exit is located.
Before your excursion starts, discuss where to meet if you get lost or separated. The last place you were together might be a good option.
When traveling with children, always prepare in advance with them whom they should ask for help, if separated, or where to meet. Also, for young children, make each of them a card with their name, where they are staying, contact phone number, parents' names, medications they are taking, allergies, and what to do if lost. Then, the child should be told to give the card only to a police officer.
On a crowded city street with a large tour group, consider carrying a large patterned umbrella and have your travel partner carry the same. In the event you are separated, open your umbrella above the crowd and find each other in an instant.
Carry ten $2 bills. If your wallet is stolen, call the police and tell them to alert banks for anyone changing $2 bills. Chances are nobody else is carrying them, and foreigners are usually too ignorant to question them.
If you are concerned about pickpockets, wrap a thick rubberband around your wallet. This will ensure that you will feel the friction of the rubberband against slacks if your pocket is picked.
