So we are beginning to get RSVPs back and there was an invitation that was addressed to Mr. And Mrs. only. They RSVP'd back for 7 people, 5 of which are all one family and we don't know where the two other guests are coming from. We are assuming guests for their kids? Even though the kids weren't invited. The people are on my FH's family's guest list and I asked my FMIL to ask them why it was so high and she said that we can't uninvite anyone at this point. What should I do? Contact the person directly or just let it go?
