We went two years ago for a popular narrator (Neil Patrick Harris), got the dining package, went to the early show, lined up about an hour in advance, and got a wheelchair spot. It was kind of a traffic jam, though, and the CM's directing traffic weren't doing a very good job.
Funny story. After all the dining package guests were seated, they asked us all to move in to make room for the standby guests. Everybody looked around and stayed where they were. We all felt the same way: we'd paid extra to be able to get the seats we wanted, so why should we give them up? They kept delaying, asking us to move in, telling us the show was going to be delayed if we didn't move in, etc.
A couple of people shouted out, "I'm not moving behind a post!"
The CM said, "You have to make room for the people waiting outside!"
The people in the crowd shouted back, "THEY can sit behind a post!"
They finally just let the standby guests in to fill in the gaps, like they should have done from the beginning. (Of course, the traffic direction was even worse getting out; we had to wait a whole hour to be able to safely maneuver the
ECV out of the theater.)
