It's funny, because I was thinking about writing something about Poor Queue Management in Disney theme parks. Mickey and Minnie's Runaway Railway, Cosmic Rewind and Rise of the Resistance all do the same thing. They structure the queue to, at some point, "no longer have a line." This is reinforced by frustrated employees. There's no line, they say! Fill all available space, they say!
If you comply, you'll soon find out that, whoops, there is still a line. And now the most sociopathic among us have been rewarded for barreling their way to the "front" of the previous room. It sucks! Just build a line and let me stand in the line, thank you! Stop trying to engineer your way around human behavior.
