Since we have them and our arcade machines in the main level of our house, our goal is always to have 10/10 of our pinball machines fully working. That being said, I do have an "out of order sign" that I can plop on top if one dies while having guests over so that I can focus on the guests rather than maintenance... I would say once folks clear I typically spend the next few hours getting things back in order before calling it a night.
