I have noticed some people posting on FB about their guests leaving earlier than they had expected (right after eating or an hour into the reception, etc).. We are planning popcorn and a late night snack for the last hour (our reception goes until 11pm) and I am now wondering if we should do both considering that people have been posting that guests are leaving early. I am wondering if it is more that the crowd doesn't want to stay later or if it was something about the reception that they didn't want to stay. Any thoughts on this?
