How did you decide which of your guests gets a plus one? We are trying to keep this as small as possible. Is it wrong for us to invite most single people without a plus one? Pretty much everyone that is not in a serious relationship is not getting a plus one. We want it small and intimate. I don't want to look back at my pictures one day and be like "who's that?" "oh, that's the guy my sister dated for 3 weeks that year!" Everyone will know other people, so there won't be a situation where they will know absolutely no one. What did you do?
