Traveling to NYC and walking tours

I'm planning to travel to NYC and stay for about a month. Since I'm the type that gets easily lost, I was thinking of taking a walking tour. Any places you guys wanna recommend?

NYC is just incredible. Whether it's food, a show, walking, skating (during winter outside in Central Park), taking a day ticket on the subway (on and off option - as many times as you want, can't remember what the ticket's called), in the harbour (Jeez - I might get for spammed on this one - I'm promoting it so much!!), throwing a few cents at the thousands of buskers - many of them are so good, oh - the choice is endless.
Just a few lines on what I did. I've only ever been there once - but I'LL BE BACK.
I got a flight from Manchester to JFK and then a bus into Manhattan. After looking at the price of a room - I moved on.... Ouch!! I spent all my nights (10 of them) in different hotels and hostels. If you plan ahead, NYC can be so cheap - just like London. Do it wrong - and oh, how it can hurt.
Once you've found a room, chill out for an hour or so, write down the address and phone number of your hotel, put it in a safe place - and start your adventure. The best way for me to get round NYC, was bus. The walking is easy too. It's so much smaller than London and simple to work out after a day or two.
You'll also find that the locals are so friendly.
My one recommendation.... If you're on a diet.... Forget the whole trip. Some of the best food in the world.
Others will follow me on this.
Enjoy your trip - lucky you.
PS.... If you're there for a month and it's within your budget - I would recommend a trip North (just over 1/2 a day on The Greyhound Bus) to Niagara Falls and across to the Canadian Falls (much bigger and nicer) and onward - another 2 hours to Toronto. Stay a couple of nights in Toronto and explore it. Another wonderful city.

If you are traveling about Montreal is a scenic 6 hour drive due North.

If you are travelling to NYC you MUST take the Grayline double decker hop-on-hop-off bus tour. It is the BEST way to see NYC and a great introduction.

This is the thing about NYC. It is an incredible city that can change in character and personality within blocks. You can't see this when you are on the subway and taxis are just to bustling at the street level.

The double decker has youup high and the live guides tell you everything. They know everything about everything. You can get off at any or all the sights and hop back on when the next buses pass by. Totally at your leisure.

The All Loops pass is good for 48 hours from when you get it stamped. That means you can get on at noon on day one and use it all day (including the night tours), then use it all day the next day, as well as the following morning until noon. You can stay on past noon on Day 3 but once the 48th hour passes you cannot get back on.

You can do the same loop more than once or just do certain portions the second or third time. You can do it once all the way around without getting off and then go back the next day and hop off to see the sites. It is GREAT!

Once you travel the loops you will be familiar with the city and will be able to walk the city or take the subways and know where you are going and what is above you.
