The long and short of the ohio pretty much gets summed up like this. Its a blue collar show with a mix of collectors/enthusiasts, and people that aren't into the hobby but think its cool. The venue has nothing wrong with it. Its not fancy, its not high end, its not the best, but it surely isn't a dump.
There area is safe and there's plenty of places to eat within 10 minute drive of this place such as mandarin house (traditional sit down chinese) right across the street, as well hambuger place. Within that 10 minute radius is just about everything else, mr hero, mcdonalds, red lobster, applebees, taco bell, arbys, wendys, Panera, bob evans, ect. So I don't know where people are coming up with "there is nowhere to eat" but they are nuts.
There are a bunch of vendors there with new and used parts. Cointaker is there selling their extensive selection of LED's every year. There's a good selection of project machines every year that are available for purchase.
I personally wish there were more vendors there with new parts sales to sell just basic things like rubbers, pinballs, and the stupid stuff everyone needs.
Lastly, as for the bathrooms. Its easy as this guys. We all know that pinball people do not strike others as the "pinnacle of class", but take into consideration that there's only 2 urinals, 2 toilets, and 2 sinks in the mens bathroom. Maybe if pinball people weren't such absolute sloppy f***s and didn't piss all over the place, we wouldn't have bathroom problems. We know damn well that those type of things don't happen at their own homes. It has been made a point over the last couple years (while at emidio) that the bathroom cleanliness was to be treated with high priority. There has been much improvement over those last 2 years and I am sure there will be continued improvements this year.
And I must laugh because I saw some people say that expo bathrooms were bad. If you are considering the bathrooms bad at a 4 star hotel as high end as the westin, then get over yourselves. That place is way too high end for us pinball guys If the bathrooms got trashed to the points that there are complaints, trust me its the users, not hotel that has the issues.
