I was wondering if anyone has advice on a Tuscan-style table seating chart. A little background on the demographics of my guests: we will have 28 guests, including about 3 children. There will be two long tables for seating. H's family consists of three sets of parents - stepfather/his wife, bio father/his SO, bio mother/her SO. Only bio parents on my side, one set of grandparents on both sides, and then we each have several siblings with their SOs attending. My best friend and her SO are the only non-relatives that are attending, everyone else is outlined above.
Any suggestions on how to seat our guests? At this point, since I want all of our parents to be seated with one another - as this might be the only time they will ever be in one place together - it seems that some of our siblings will be seated with them and most of the other table will be completely made up of siblings & their SOs. How do we decide which siblings are to sit at the "Adult table"?
