Hi Saurabh1985,
Here are a few:
Do you research online before you choose a hotel--they are expensive, but there are always deals to be had. Think about which neighborhood you want to be in, and start with the hotels near that location (i.e., Times Square, Financial District,Upper WestSide, Upper East Side, etc.). If you want to be near Times Square for shows and attractions, a hotel down in the financial district will not be convenient, and you'll either spend lots of time on subways and buses, or lots of money on cabs.
Be aware that the pickpockets know how to spot unsuspecting tourists. While you can't help the fact that you are a tourist, dress for security. This is especially important in crowded areas, like Chinatown. If you're a woman, bring a cross-shoulder bag that can lay flat across the front of your body. No open bags swinging from your shoulder. Wallets should never be in your back pocket. Move it to your front pockets or an inside jacket pocket.
If you're paying a cabbie or making a deal for your fare, never pullout a stack of cash and ask "how much?" A good friend lost $200 in a flash doing that in front of Grand Central Terminal.
Wear comfortable shoes that you've broken in already. New York is a fabulous city for walking and looking at the sites. But, pounding the pavement all day in new shoes will result in blisters and aching feet at night or the following day.
If you're up for taking the subway, get a laminated map to tuck in your back pocket or purse. They usually have them at the cashier desk in the big book stores, like Border's. Study the map before you leave your hotel and make your plan for how you will get to your destination. Figure out your connections, so that when you walk through the turnstile, you already know what signs (Uptown/ Downtown/ Express/ Local) you're looking for. Then, when you get in the subway car, look for the lighted line map. It will show (with lights) which stops on your line your train will make. Once you confirm that you can get off at your chosen stop, sit back and watch humanity all around you. It can be fascinating.
And finally, take pictures! Yes, you'll look like a tourist, but New York changes overnight. It won't be the same when you come back the next time!
Bon voyage,
