I went to the Empire State Building today and it was obviously very busy. The queue to get in was 1h30m long so I decided to come back later, and maybe even book tickets in advance. Now, I see that various ticketing options are available so I'd like some elucidations.
How many queues are there to go in the Empire State Building? Does purchasing tickets in advance allow me to skip the queues? If so which tickets and which queues? How does one jump the queues? Is there a separate entrance for ticket holders?
