To me, I had to watch it again to understand that.
Why in the hell would they make a HUGE mistake like that. Is it because doing an actual High Capacity Dark Ride that's simple in scale and not expensive being too hard for them? Because, when looking at Universal; they have done well with small budgets.
And it's a real shame too, because Frozen in my opinion can lead to some interesting concepts for a true Dark Ride instead of going to the porting status. Either way, if DL gets Frozen; I wouldn't be a damned bit shocked that it happens again for them.
