I sent out all the invitations February 23, which is 7 weeks before my wedding on April 13th. I asked, on the invitation for people to RSVP via the reply cards by March 23 because I needed the official count to the caterer by the 30th and I wanted to give a little bit of leeway for late RSVPs.
So here we are a week from my wedding and my fiance's mother left me a voicemail saying that about 15 people (3 of whom we didn't invite) have RSVPed to her and she wanted to make sure I added them to the count.
I called the caterer and asked if there was any way they could add any more guests, they said no and the contract I signed did agree to letting them know the final count 2 weeks before the wedding and I can't add or subtract anyone after that so I can't really argue with them.
My fiance just got home from his tux fitting and I told him what was going on. We agreed that there was nothing to be done and he would just call his mom and tell her that since the people RSVPed 2 weeks late and not even to me, as requested, they won't be able to come. He also asked about the 2 people who we didn't even invite, she said she invited them because they were family friends. He told her that she shouldn't have done that (meanwhile I was ready to spit nails over her having the audacity to invite someone to our wedding).He told her since she took the RSVPs instead of telling them to call us and invited the other 2 people, she will have to tell them they can't come.
Now she is throwing a fit. about having to tell them. I am afraid that she just won't tell them at all so I am thinking about sending her a text message saying that the caterer won't add more people so if these people show up, they won't have a place to sit (handled by the caterer) and they won't have food to eat and it will be very awkward for them.
