This will be a long one ... FI and I got engaged, talked about who we'd invite and our guest list was 110. We started looking for venues, fell in love with Casa Feliz, and booked it. I then get a guest list from FMIL with 65 people on it (57 in addition to our 110). We can only have a maximum of 118 guests and even with that many people it is like sardines in a can. I have a large family but have decided only to invite my immediate family, family that I have close relationships with and close friends so that I can make room for FI's family. I tried explaining this to FMIL and she did take some people off the list but I am still at 132 people. The bulk of the list is FI's cousin's, who are all 40+ years old, married, and all with 2 to 3 children. I should mention that none of the cousin's or children were on the original list that FI made, nor does he have any relationship with these people. Everyone keeps telling me not to worry; not everyone is going to show up but I am really, really uncomfortable inviting more than we can fit in this place. FI refuses to change venues to solve this problem and the other option I can think of it to take his cousin's off but I have tried reasoning with FMIL and she is adamant about inviting them. She even went so far to say that if everyone RSVP's yes and there are too many people she would "take care of it", as in, uninviting his cousins. Can we say tacky?I am trying to be fair to everyone so my latest idea is that we make it an adult only wedding. Most of the people I plan on inviting don't have children and eliminating his cousin's kids would be like 15 people right there. The only possible problem with that for my guest list is that my cousin Parker is 12. Do I not invite him then? And my cousin Marni would be coming from Boston with her husband and son (4 yrs old). I obviously can't say, my people can have their kids but your side can't, right?I need some kind of middle ground where everyone is okay. I just don't know what it is. Any thoughts or ideas?TIA!
