One suggestion for next year.
A repair area and a pinball dolly to get there. My STTNG started having problems mid-day Saturday, but I couldn't manage to fix it in the middle of a row with all the people around. I did fix it (temporarily) during the after party and it lasted until about 12:30 on Sunday. Given more room and all the knowledge available in the room, I could have gotten it running. Looking back I probably could have moved it behind the inflatable screens to work on it.
Thanks Whysnow for lending a multi-meter. Also appreciate the people who texted the issue instead of just walking away.
I did pull it early, had it been running I would have left for my family obligations and came back for it at 6.
