I attended the Late Night Show in Rockefeller Plaza in New York with a friend, and it was absolutely incredible. The whole thing takes just over 3 hours, including the waiting line, the wait after getting in, the show and the off-camera breaks during the show. The team was great to work with, everything was well explained and supervised, and Seth Meyers also took time off-camera to chat with the audience, which makes it really more pleasant. It's a truly American experience, a must for tourists who want to see the backstage of this kind of show.
