There is a 15-week "Atlantic City Fan Xpo" convention going on this summer that is still looking for programming to fill some of the weeks. It looks like more of a "nerd/geek" con with eSports, board games, comics, etc. They already booked the Showboat hotel for space, and could be open to doing a pinball show one of the weekends if someone reached out to them (I would but I only have one machine). Not sure what the attendance will be because this is their first year doing it and everything is coming together late, but it might be a way to have an AC show without doing much legwork (i.e. arranging the space, marketing, etc.).
