I think the falcon queue will settle at the 80 minute mark nightly on high crowd days, it is really a fast loader if people would listen to the cm calling their crew color.
For theme and continuity the holding room is awesome but it might have been a mistake to put it where it is in the queue. I don't blame people for wanting to spend time in there but in reality you only have about 30 seconds to walk around and take pictures before your color is called and the efficiency of the ride depends on people being ready to board as soon as the color is called .
The holding room is already a topic of discussion with the managers on how to make it a better experience for both guests and efficiency of boarding
