My Fiance and I are getting married in a hotel ballroom, but half is being used for the ceremony before the reception. Do they leave the tables together and set up in the closed off half and then just slide them over or do I need to be prepared to have someone (DOC or sister or someone) help flip the room over to the reception space? They are doing it at cocktail hour. We are probably going to do all the centerpieces ourselves, so there will not be a florist there to set it up.
