Is it better to stay in Manhattan or a different borough?

Stay in Manhattan if you want to be close to the main tourist sights. Stay in Long Island City (Queens) or Downtown Brooklyn for cheaper hotels that are still only a 15-minute subway ride from Midtown.

Should I buy a CityPASS?

Only if you plan to visit at least 4 of the major attractions (Empire State Building, MoMA, etc.) in a short window. If you prefer wandering and casual sightseeing, you'll save money by paying as you go.

Planning Your First Trip to New York City

Focus your first trip on one or two boroughs to avoid spending your entire vacation in the subway. Spend at least 5 days to see the major icons without rushing, and always prioritize booking your landmark tickets at least 3 weeks in advance.

Map out by neighborhood, not by landmark. Don't jump from the Statue of Liberty to Central Park. Group your activities geographically. For example, do the Financial District and 9/11 Memorial on one day, and Midtown West on another.
Master the subway early. Download the 'Citymapper' app. Skip the single-ride MetroCards; simply tap your contactless credit card or phone at the turnstile (OMNY system) to pay your fare.
Book timed-entry tickets. Museums like the MET or the MoMA, and observation decks like the Top of the Rock, require timed entry. Book these online 2-3 weeks before you arrive to ensure you get a slot.
Pick one 'expensive' activity per day. New York is pricey. To balance your budget, plan one big-ticket item (a Broadway show or a museum) and pair it with free activities like walking the High Line or exploring Central Park.
