Has anyone created signs to keep guests out of the reception space until dinner? For reference, our ceremony, cocktail hour and reception are all on the same property. I don't want people wandering around the reception space, putting their stuff down, moving chairs until it's time for dinner in the reception area. I know this is difficult and doesn't really make a difference on the big day, but has anyone succeeded with keeping people out? What worked? I'm not to the point where I need to hire security. Its more of a want than a need. TIA
