I am having trouble with the final count of our guest list. We want a small wedding somewhere between 120-130 people. I had a guest list all made out and I was ready to send out save the dates. Until my mother in law to be told me she had already sent out her own save the dates for our wedding. I was fine with that thinking "hey saves money for me". until I had found out that she had added people to the guest list from her side of the family. Now our final guest count is at 148 and I am completely stressing out because not only am I freaking out about how we are going to pay for those extra mouths to feed but I also face overcrowding in our venue. I am trying to size down the guest list from what I can (meaning everyone that hasn't received a save the date) and I am getting upset because I feel like its a little more important that my FI and I have the friends and family there that we want the most and it is starting to look like we might have to drop a significant amount of close friends from our guest list. I feel that this is unfair because it is our wedding and we cant even invite our close friends, and yet she sent save the dates out to her "old best friends from high school" and people that my FI doesn't even remember/know. SO to fix the problem I am wondering how rude it would be to send out an invitation that is only inviting some of her people to the dance portion of the reception. I figure I can't just uninvited them but if I invite them to the dance only, then I don't have to worry about over flowing and extra dinners. We are already doing this for some of our coworkers and this is the only thing I can think of that can fix the problem my mother in law to be created. Any advice?
