^ Yup, I practically don't do cons any more for the exact reasons, but probably no way of turning back the clock on this one.
I'm running restaurants these days and pay attention to that industry in particular, and chains like Olive Garden/Applebees see their business dying off - possibly because millennials have different habits. I don't know, but it seems cosplay is here to stay, run collectors and box divers are a dying breed, and the current con situation, pretty awful for comic collectors, is the organizers way of reinventing their product to stay in business.
