18 days out and a guest let me know she and her SO wouldn't be making the wedding. And...they knew they wouldn't when they RSVP'd with a big fat yes almost a month ago but just didn't want to tell me. Our venue is very small so we had to be pretty cutthroat with our invites, that's two seats we could have extended to others wanting to come. Too late to fill them now? I feel bad asking anyone this close to the date. I don't want someone to feel like an after thought but would love to fill the seats.
