I'm searching around for preliminary info on reception sites. Some sites (like museums, etc) say that they are unavailable until 6:30 and the like. Is that typically when your wedding can actually START? Or is that when you can start setting up? For those locations should I add another hour or so of set-up time? (In other words, in the previous example, should I expect that the wedding can't start until 7:30pm?) Or do they typically factor set-up time in and the wedding itself can actually start at the time listed.
I know that the best way to do this is to just call all the places, but I'm just wondering if there's a standard rule so I can see if some places I can just rule out right now.
