Next time I go to NYC, I'll likely stay in Newark or Queens. I've done all the tourist stuff in Manhattan (Times Square, Central Park, Empire State Building, Broadway etc). I'll probably go back again for the US Open, and usually I'm just at Flushing Meadows all day anyways watching tennis, or a baseball game later at Citi or Yankees Stadium. Plus its easy to get into the city from Queens or Newark. Light rail commuter trains are only like 15-20 mins and take you right into Central or Penn Station.
