My dad keeps asking me when we are going to have a walk through w/ the caterer and my DOC at my venue? What exactly do you do at a walk through? How long does it take? Who do I need to have there? Are they just going to show me where everything is going to go? Because I've seen my caterer's floor plan already. How far out should you schedule one w/ the necessary vendors? I don't see anything about this on any checklist that I have about this...
