New York

If you are staying in the city, there is no need for a car. It's very expensive to park in Manhattan. I take the subway, as do 5 to 7 million other people, everyday and find it convenient most of the time. Although on the weekends there can be delays or detours. Those detours rarely affect trains in Manhattan though. If you are staying in Manhattan, you'll likely walk a lot also. And there is never a shortage of cabs either.

If you have the time, Coney Island is worth visiting.
