You'll look—and feel—less conspicuous if you replace maps with apps. If you have a smartphone or tablet, download a subway map app from the MTA's website to help you plan your trip (by fastest route or fewest train changes), find nearby stations, and stay up-to-date on any service disruptions. Most major NYC attractions—from Central Park to the Met Museum—have their own apps to help you make the most of your time so download accordingly before you visit. Even better, download just one app—the Fodor's NYC app—for attraction overviews and handy suggestions of what's nearby.

New York City is a safe city, but it's still a city, so keep jewelry out of sight on the street; better yet, leave valuables in your hotel safe.

When in bars or restaurants, don't hang your purse or bag on the back of a chair.

Expect to have yourself and your possessions inspected thoroughly in such places as airports, sports stadiums, museums, and top attractions. Police officers reserve the right to check your bags before you pass through the turnstile to enter the platform.

We suggest politely ignoring panhandlers on streets and subways, people who offer to hail you a cab, and limousine and gypsy-cab drivers who (illegally) offer rides.
