Everything’s been going pretty smoothly during our the last month of our countdown until the wedding. We’ve got our final headcount in and our seating chart is (was) finished and I’ve been slowly working on our pinecone table cards. Tonight my FW’s aunt, who were pretty close to but is extremely overbearing texted her about the seating chart, asking who was sitting where. She apparently then demanded that she should be at the parents “head table” because her brothers are both sitting there and it’s only right. My FW’s Dad and his brother, who is my FW’s god father will both be at that table. We would have put her at this table as well had she not had her children's spouses/friends (her 3 kids are in our bridal party) and some of her husbands family attending the wedding. We wanted her to be sitting with that group. The “head” parents table is both my FW’s separated parents and their SO’s, both sets of grandparents, and then her uncle and his wife. FW feels like we need to redo most of the seating chart just to fit her in at this table. We’re going to have to shift at least 6 tables.
What to do? I want to tell her no and that it’s too late. And my FW already has made that apparent saying that we laid out all tables with the venue for set up and have written name cards. Is she right or is this just plain rude?
