The dinner package section was completely filled long before show time the night I was there.
But that was because so many people were sneaking in. They seemed to be short of CMs because there was no one down at the front to keep people out. Guests would try to enter at the back and be told it was reserved seating, so they would go down to the front and slip under the rope. I watched dozens and dozens of people do this, kids in tow, teaching them such an invaluable lesson about rules and how to break them.
It got completely out of hand. When the CM tried to go down to the front to stop people there was a mad rush at the back.
I knew about leaving via the Oscar route because I had read about it in Tourguide Mike. I asked the CM when I came in, just to confirm, and was told yes, that was the way we were supposed to exit.
Mind you, they did not let use that route all the way to Oscar's when exiting. Oh no, they had to reroute us just before Oscar's to the street from TOT so we could walk past all the lovely shops on our way out. But we were still far enough ahead of the crowd to make me happy.
