While out in public:

Do not display large amounts of money. Place small amounts in different pockets to assist with this or use credit cards or travelers checks.
Make copies of your credit cards front and back and place them in a secured place for your records (room safe). This can be very useful if you need to report a lost or stolen card.
If you see something suspicious, call 911 immediately. When you return to your hotel, use the main entrance especially in the evening.
Be wary of solicitors. Use reputable places of business for all your entertainment transactions.
Travel in pairs or groups if possible.
Always have a meeting place for the kids to meet you if they get lost.
Teach your kids your name, house phone and cell phone number.
Small children should always be led by the hand when crossing the road or near busy streets.
Small children should have their name and phone number placed on their clothes label or the inside of a shoe flap with a permanent marker in case they are lost.
Use the sidewalk and pedestrian crossings.
