We have hired a castle for the day and are getting married there, having the w. breakfast there and the evening do.
We will get wed, then go out onto the terrace for pics and champagne, and while that is happening the grand hall is being set up. As we have the run of the entire castle we have lots of rooms to wander into so space for us lot while it is being set up is not a problem. We are getting married in the largest hall of the castle, and are having out W.B in that room too because we have quite a lot of guests. I think (at a guess) it will take them about 45 minutes to set the room up for us.. need to check that with them though!
