Many brides give me a long list of groups they want on the day. They have no idea how long it takes to do so many groups. For example ten groups taking 6 minutes each (depending on their size and the discipline of your guests) will take about an hour to do. It’s difficult because you also don’t want anyone to feel left out. I also recommend that any photos that you want done as individuals is done before the ceremony to take a little pressure off the schedule after the ceremony. For me it’s really funny when a bride swears at me when I produce HER list at cocktail hour.
