I'm sure it's been asked a billion times already but .. I'm curious as to how most of you are handling the invitations when it comes to deciding whether to add " & Guest"... Are there certain guidelines most brides follow? I was thinking, for the younger crowd, to just do them SOLO. But then in the case of my brother who's going to be 20 at the time, he's been with his gal for almost 4 years, so I'd definitely have them both on the invite. Help.
