Quoted from vicjw66:
Change the expo from wed-sun to wed-sat because Sunday is just a packing up day and nothing really going on. If someone decided to go just on Sunday they would be very disappointed.
The tough thing about this suggestion is that if you make it Wed to Saturday, people will pack up early on Saturday and leave then.
It's an issue with any show. With the MGC, we only run two days (sort of a third mini night), and we keep only about 2/3rds of the games there until close on Sunday or close to it.
Inevitably, people don't plan on staying at the hotel, and leaving a bit earlier seems more responsible. I get it. Expo, with its five day format, experiences this significantly more than even we do. A possible solution would be to sell extremely discounted tickets for Sunday, but I don't think Expo drives much attendance that day anyway.
Expo targets those who really know the pinball community, and because those visitors are pretty savvy to the show before they get there, I doubt many if any people are surprised by Sunday each year.
