well it depends where youre flying into, jfk, laguardia, newark… but cab fare is usually flat rate around like $45 into manhattan. i guess i may have a bias opinion since i used to spend a lot of time in manhattan, but basically find a hotel thats actually in the city, or else youll be wasting time getting to the “sights” every day. if you fly into neward you can just get a bus for like $14 into port authority, and then from there you should be able to hoof it, dont quote me but a metro pass should be like 14bucks or something for 3 days, unlimited rides… id say ur dead on with airfare… id skip the nightlife, its gonna be $$$, but what i would reccomend would be south st. seaport, its pretty chill there, and there are some bars, maybe ill post up some pics… dont get suckered into those touristy restaurants, the food sucks balls, and youll walk out with an $50/person bill. you might want to check out little italy, its really chill, the problem is that to get there most likely when you get off the train, you have to walk thru scummy part of china town…
