My fiance and I really want to pick a venue we love but that maxes out at 250 guests and our list is currently 270. We know that the general rule of thumb is that 10% of invitees won't attend, however, I feel like inviting 20 over the max could be a risk for us because of WHO these invitees are - people who will most likely come. Does anyone have any advice on how to handle mailing out "A" list invitations far enough in advance to allow time for enough of them to hopefully decline so that "B" list invitations (people only invited if enough A listers decline) can be sent out within the proper 6 weeks prior to the wedding?
