My mother-in-law has planned a wedding rehearsal dinner, and I am not sure whom should I invite in it. I am really anxious to know, if it is really mandatory to invite out-of-town guests as well, because the marriage has actually been planned in a haste, and I don’t know whether they would be able to make it for the rehearsal dinner just the day before my wedding. Can somebody please tell me how shall I plan the invitations for my wedding rehearsal dinner? Thanks.
