New York City, the largest city in the United States, consists of 5 boroughs: Manhattan, Brooklyn, The Bronx, Queens and Staten Island. A very important global city in the business, finance, media, technology, art, fashion, entertainment, research and education sectors. Being cosmopolitan between its ethnic neighborhoods, Little Italy and Chinatown are the best known. It receives about 50 million tourists a year and its most visited places are Times Square with its lights and shops of all kinds and Broadway with theaters, shows and restaurants. It also counts with several bridges, parks and the very famous skyscrapers. Wall Street is its financial district where we find the Stock Exchange and the One World Trade Center with the memorial.
The fastest way to travel is the metro but note that the same metro ticket can be used to catch a bus.
If you like walking, do not hesitate, the city is very easy to go and at every step you will find something to see or something to do.
A beautiful day of walking and shopping could start at Central Park and continue in a straight line to Times Suqare, you will be amazed to find so many famous brands stores and you could end the day between the lights of Times Square in one of the restaurants or cafes around.
New York City is not a city where you can really save money so one way to save would be to find a well-placed hotel and take a room with the included breakfast. You could have a great succulent meal for almost the same price as you will pay for a coffee and a pastry; that will make that right after that you should stop eating something again.
