We are at our limit with having 40 guests for the rehearsal dinner! We have a lot of out of town guests and family members that didn't even make the cut. Is it rude to put on the rehearsal invite "Plus ones only if married. We apologize for any inconvenience." Is there a better way to word it? Or should I just leave that off completely and suck it up and allow plus ones? My feeling is that it's only the rehearsal and I don't want it to get crazy huge or out of control.
