New York becomes easier when each day focuses on a geographic cluster rather than crossing Manhattan repeatedly.
Day 1: Midtown and a skyline view
Start with major Midtown sights and one observation experience.
Day 2: Central Park and museum time
Use the second day for the park, museum district and nearby neighborhoods.
Day 3: Downtown and Brooklyn Bridge
Combine Lower Manhattan with the waterfront and Brooklyn Bridge.
Day 4: a neighborhood-focused day
Use the final day for Brooklyn, Queens or a Manhattan neighborhood that matches your interests.
