This is such an impressive building! Two major tips: 1. Buy your ticket online to skip the first line. There are two lines - one to buy tickets and one for the elevator. 2. If you can't buy your tickets online, go early in the morning. I got there at 9:10am and barely had to wait in ANY lines. I was up at the top of the building in 10 minutes. The night before when we tried to go, the line was 1.5 hours long. Also don't go when it's hazy or cloudy out. It will obstruct your view. Tickets are $16.00 and you can get an audio tour for $6. It is totally worth it to get the audio tour. You could see the entire city. It was amazing at the top of the Empire State Building!
