Quoted from ktrain315:

Agreed. Many were packing up by 1pm last year. If the vendors want to leave, fine...most people aren't buying vendor stuff Sat afternoon anyways.
Extending the show till Sunday is brought up every year but still hasn't taken affect.
I respect owners who want to shut down their machines at the end of the day for whatever reason, its their machine. But, having games available all night could work too if you really wanted. To make it work, on the floor plan you would have a section/area of games that will be available all night. People could set up there when they arrive, or move there later in the day and only machines in that area will be on and available. You may need to have someone police the other area to make sure people are not turning on and playing those machines.

Quoted from Gnatty:

So then don't schedule your time at the show for Saturday, go Thursday and Friday. People who bring games, vendors and flea market sellers are the ones who make the show a success and if they do not choose to stay on Saturday due to travel and the time it takes to load and unload, then so be it. I side with those people on this one. People have ample time to take off work and change their schedules plenty of time in advance to attend early on at the show.
