Hello you all. I need help with my guest list. Our original list for our guests was around 85. We are now closer to 105!!! This is an issue for me as I am paying for catering and it's the major expense. This would add an additional $400 to the amount and I didn't budget for this. I have one guests who wants to include another family member to her plus one, his family invited people who were never sent an invitation and not on our list, but because we are doing our RSVP through a website, they were able to go and include themselves!! I want to have a list and stick to our original list so if they were not technically invited, they can not be seated. Is this rude? Should I just chuck up the extra money? Please advise me, because I'm about to blow a fuse. P.S, the wedding is in 17 days.
