Our wedding ceremony is 4pm. The reception site is roughly 8 minutes from our ceremony site. With a ceremony start time of 4pm, we anticipate it to be over by 4:30, and have a receiving line out the door. We will be making photos afterward (and planning for it to be as speedy as efficiently possible), but have no cocktail hour at our reception site...so no time to stall the guests as they wait for us taking photos. We were planning on our guests getting the go-ahead to begin eating (heavy hors d'oeuvres) shortly after their arrival at the reception site, while we finish up photos. What do you all feel is the most appropriate take on a timeline for this? Is it realistic?
