Here is another idea for ways to enjoy spring break in the city: Go to the Empire State Building! Yes, it's cliché, but there's a reason for that. The views are amazing and at $20 a ticket, surprisingly inexpensive for a New York experience.
Getting there is half the fun: The entrance is at 34th and Fifth, but before you actually get inside the building you'll have to navigate an obstacle course of people trying to upsell your experience. Do you want to buy a $10 map? Do you want to see a movie about the building narrated by Kevin Bacon? Do you want a New York cabbie to whisper the building's secrets into your ear? All of these experiences and many more can be yours -- for a price.
