New York City can be one of the most expensive destinations in the United States (and the world). You can pay more for lodging, dining, and transportation than almost anywhere else; however, on this site, we steer you to the best values for your money at every level.
In terms of how much to bring: not that much in cash. You never have to carry too much cash in New York, and while the city’s pretty safe, it’s best not to overstuff your wallet (although always make sure you have at least $20 in cash for small purchases).
ATMs -- In every Manhattan neighborhood you can find a bank with ATMs (automated teller machines) every couple of blocks. Most delis, many restaurants and clubs, and other stores have an ATM on premises, so if you need cash quickly, you’re probably never more than about 100 feet away from one. (Though keep an eye on the fees imposed for using the ATM; they will go on top of whatever fee your bank charges; and note that in some bars and clubs, where you can’t leave once you’ve paid your admission, the withdrawal fee is hefty.)
