My FMIL has offered to pay for the rehearsal dinner. We are planning on having it at a restaurant near the rehearsal location which we have already put a non-refundable deposit down for a private room. Cost is about $20 a person and we will have between 30 and 40 people attending. We have invited all of the significant others but FMIL just got laid off and is worried she now can't afford to pay for everyone. The FI and I don't think that we will be able to cover the cost of it either. Would it be rude to offer to pay for only the wedding party and ask significant others to pay for their own meals if they would like to attend? They won't be at the rehearsal so they would then just have the option of whether or not they wanted to meet us for dinner. Is there another option that I'm missing?
