New York is one of the most diverse, exciting, and sophisticated cities in the world. It sees itself as the centre of the universe and, like few other cities, can probably justify the claim.
Highlights include walking in Central Park, the view from the Empire State Building, long twilights in Greenwich Village restaurants, and the bustle and buzz of Times Square.
This is the natural home of the skyscraper, and the skylines are both stately and inspired.
Quick Tips:
New York is made up of lots of smaller neighbourhoods, e.g. SoHo, Harlem, Upper East Side... all names that you'll have heard from television and the movies. As well as doing the big sights, it is worth spending some time just strolling, eating, and soaking up the disparate atmosphere in some of the neighbourhoods.
New York has lots to do for everyone, and that includes children. Don't underestimate a young child's interest in the 'adult' sights, big buildings, and bright lights, and Central Park has lots that will interest kids. If that can't keep them happy, the Toys 'R Us in Times Square has floors of toys, displays, and an overpriced ferris wheel. Whilst not easy, it is possible to make it out alive without buying anything.
Best Way To Get Around:
For a city so large, New York is remarkably pedestrian-friendly. Between the subway and the shoe leather, there are few places that are difficult to get to.
The street/avenue grid makes navigation easy.
The subway itself is efficient, relatively clean, and not nearly as crowded and daunting as you would expect. Most of the lines run north-south, with few crosstown lines beyond Midtown; however, with a little planning, this need not be a problem.
A flat fare of applies for every trip, and there are a number of travel-card or multi-buy options to save money. Consider your plans beforehand, because even the most ardent sightseeer would have trouble averaging four subway trips a day.
