It was a Saturday around 2 in the afternoon and there was absolutely NO line. That was great. My daughter and her friends had fun taking pictures with some of the celebrities. The only unfortunate thing is that there were many historical figures of which they had zero interest in looking at.
If you have heaps of time in New York, this is worth doing. It was right next to our hotel so it was convenient. There are some celebreties that were not there though.
Worth a visit. However be aware that the queues at the end of the tour to purchase photographs are long.
We waited for at least 45 minutes to be served.
