For what it's worth I went to a show there a month or so ago and they were doing pat downs and searching bags. I'm sure you'll be fine just hiking around, but it may get more complicated if there is a show going on.
It depends on the show. Also if you're dressed respectable and with your family the patdown will probably be less intrusive. I would not advise carrying anything larger than an LCP/LCR at that venue. If you have a NAA mini you'd do best carrying that instead.
