Looks like this D23 Expo could be jam-packed, more so than usual. I'd love to check it out sometime, but every D23E they've had recently has had enough moments of f'd up ops/crowd control that I'm deterred on wanting to go. I'm generally pretty good at handling big crowds, but people missing panels due to a wonky/slow entry process, people not getting let into panels because they're quote "full", but confused friends in the panel show clearly otherwise, and then you have the animation panel disaster from the last Expo...just one of those is a big NO from me.
For a place that I felt had great ops and crowd control, the D23 Expo just makes them look like amateurs.
