Safety The crime rate in Princeton is significantly below the national average, and it is a largely safe, upscale suburb. Of course, it's always wise to take the usual common-sense precautions: Avoid deserted areas, especially at night, and don't venture into public parks at night unless a concert or another event is attracting crowds. Keep money and valuables out of sight, always lock your hotel door, and don't carry too much cash on you.

Smoking Smoking is prohibited in public places and places of employment, including restaurants, bars, and nightclubs. Exceptions include designated smoking rooms in hotels, retail tobacco stores, and private clubs.

Taxes Hotel rooms are subject to a 7% tax, and the local sales tax is also 7%, which is applicable to all purchases. In the U.S., there is no value-added tax (VAT) or other indirect tax at the national level.

To Make International Calls To dial international numbers, dial 011, then the country code, then the phone number. The telephone system in the U.S. is run by private corporations, so rates, especially for long-distance service and operator-assisted calls, can vary widely. Generally, hotel surcharges on long-distance and local calls are remarkably expensive, so you're usually better off using a public pay telephone or a cell phone if you have one with you. Many groceries and convenience stores sell prepaid calling cards; this can be the least expensive way to call overseas.

Time Zone New Jersey, like New York, is in the Eastern Time Zone, which puts it 5 hours behind Greenwich Mean Time (GMT-5).

Tip the doorman or concierge if he or she has provided you with a service, such as calling a cab or obtaining hard-to-get tickets. Tip the parking attendant 15% of the parking rate. Cab drivers should get at least 15% of the fare. In restaurants, bars, and nightclubs, tip wait staff 15% to 20% of the check, bartenders 10% to 15%, and checkroom attendants $1 per garment. Skycaps at airports generally get at least $1 per bag, while hairdressers will expect 15% to 20%.
