Hopefully your wedding will be an exception and all your guests will stay to the end. If they don’t, however, do your best to remember that your guests do love you and they did have a good time. Their early departure is not about you or your wedding; it’s about them. And the benefit to having people leave early is that those who remain are the intimate crowd who don’t consider the reasons to leave as valuable as the reasons to stay. They are most likely the ones whom you cherish anyway.
