A first-timer plan for New York: landmark clusters, one skyline view, walking, and subway-aware pacing.

Group Lower Manhattan and the Statue of Liberty, Midtown viewpoints and Times Square, and Central Park with a museum. Crossing the city repeatedly burns a New York day fast.
Top of the Rock, the Empire State Building, One World, or the Edge each give the view. Choose one, ideally near sunset, rather than paying for several.
New York rewards walking, but the subway saves the long jumps. Get a tap-to-pay card, keep a rough route, and leave room for a neighborhood meal between sights.
