I need some help! We are doing a more informal reception with food stations and heavy hors douvres. We plan to have a mix of regular round tables (8 ppl per table) and high top tables w 4bar stools. My FMIL is very old school and wants us to do reserved seating for family and elderly guests (understandable). But our family is huge and makes up 100 out of our 175 guest list.
So my question is-should we do a seating chart since over half of our guests will have reserved seating. I don't want to insult the handful of non-family members and just stick them at the high tops by default. I don't want confusion but I also don't want to lose the "casual" vibe that we are going for. We want our guests up and mingling, dancing, getting pics at the photo booth, not seated at the tables all night.
Also-if we do reserved seating for only a handful of guests, how should we let them know where to sit? Signs? Place cards just for them? I just don't want to insult the non-reserved seat guests.
