I got kicked out with a ton of people every midnight.
Here's the thing, because I get that the vendors are tired and burnt. The hall really serves multiple masters. There's a big difference between everyone wanting to line up and play Dialed In vs people wanting to buy flipper rubbers or a playfield. Or the new Sterns. Or whatever. Those aren't really "vendors" in the traditional sense.
If there was any way to maintain access to the games but let the vendors shut down and have their wares be safe it would seem to be to help everyone.
