So, I am in need of some major advice! The MOG had given me a list of guests to invite way in advance of the wedding. She said there were about 60 people on their side that would come. I accounted for 80 to ensure any last minute add-ons were taken care of. Now, she has added more people to the list... and she is still going!! I thought there were going to be about 180 people (combined) attending my wedding, but now the list has gotten to 250. She went from having 60 people coming on her side to 160!!  **Now comes the big problem... I booked a venue assuming that 180 would be the top amount of people attending. The venue holds 200 max, so now I don't know what to do about the extra 50!! I have already slimmed down my side of the invites to the bear minimum, but she is still adding her friends and co-workers! I feel like it's a little unfair, since I planned around the number she originally gave me (and I would have planned around everything that she wanted if she just would have told me a more realistic number to begin with), but now she is changing her mind. What do I do?? HELP!!!
