Quoted from robotron911:No sane person would go to Expo for the pinball play. You go because of the seminars and schmoozing.
This is the right answer. You play because you're there, you don't go to play. The people are what make it a special event. You go to hang out with your pinball friends who aren't local, it's been the event everyone travels to. Maybe not anymore, I dunno. I'm skipping it this year and I'm not alone. Sure it won't be a ghost town or anything though.
And Sunday is useless, no reason to be there for it.
