How much money should I need on my trip to NYC for two weeks?

So you're not including hotels in your question? You could easily do it on $100 a day for food, drink and transportation. I agree with the others that say $200 per day - you would be doing it right - but I just want you to know that you can do it on less. You can easily eat for $50 per day! Especially if you go to the buffets in Las Vegas and some of the less expensive places to eat at the Wharf.
