Our invitation suite is semi-informal and the invitations themselves are large, so we aren't using inner envelopes. We are also having an adult-only reception. When I ordered our invitations, it never occurred to me to put "___ out of ___ attending" on the RSVP card. Now, without inner envelopes, I'm concerned that our guests will be confused about who all is invited to the wedding. I don't want to have to call fifty people and tell them that they RSVP'd for too many.
I feel like we have 2 options: We could either address all guests on the outer envelope (Mr. So-and-So and Guest," or we could print a small insert and paper clip it to the RSVP card that says "We have reserved two seats in your honor!"
I'm leaning towards the 2nd option because I'm afraid the outer envelopes will get tossed without our guests looking at them (or they will see "Mr. & Mrs. So-and-So" & assume everyone in the household is invited). Would it be tacky to print an insert & clip it to the RSVP though?
