Ok so here's the back story:We finalized the guest list a long time ago and had about 210 guests. FMIL was fine with this, but then a couple months ago, remembered she had another 24 people she wanted to invite. 6 are from her work (she's a nurse). The rest are from this prayer group she's been in for about a year. The venue only holds 220, so we would be over capacity by a bit. I'm really not comfortable chancing it, even though I'm sure we will have 10-20 people RSVP "no". I explained to her (nicely) that this would put us over capacity when she told me that and that we would need to figure out how to make it work. My parents are paying for the majority of the wedding, and have already cut their list more than they probably wanted to in the first round. FI and I have also cut down to only people that we have to invite with our friends. So apparently she just told FI that she verbally invited the prayer group, but told them they couldn't bring spouses! I feel like that is beyond rude. I mean, they're her friends, but still. I don't know what to say because FILs are contributing some money too. Should I just chance it and be over capacity or not follow ettiquette? I'm really frustrated right now!I know 220 sounds like a lot of people to be at bare bones with the guest list, but we both have huge families (my mother and FMIL both have 8 brothers and sisters).
