Unless someone is selling it in the Orange or Purple Halls, there is nothing to worry about. Those are the only "Public" halls
That is, unless the family decides to take advantage of the one time guest admission to the member halls.
Could they have done so before the dealer halls were opened to the public? ----- yes, but they'd have to know about the show first, and be enticed to attend.
I guess that most families will find the dealers halls to be more than enough, so this probably will not be an issue for anybody.
