Ok I figured I'd just start a new discussion so I don't hijack Soon to Be Mrs R's Post... https://www.weddingwire.com/wedding-forums/seating-charts/49118d5eccc6443d.html
Hayley showed me this discussion: https://www.weddingwire.com/wedding-forums/psa-open-seating-sucks/81d89409fbf57f36.html?page=1
After reading it and reflecting a bit...here's my two cents:
1) If you are having a plated meal, assigned seating is pretty much necessary. The exception to this is if you create different colored seating cards (or something along those lines) and each guest grabs their color and puts it at their place setting. Still, some venues with plated service require assigned seating so they know in advance.
2) If you are having a buffet or family style meal, then it is certainly not necessary, but certainly can still be assigned if you want.
3) In general, smaller weddings don't need assigned seating and larger weddings do. However, I consider this more of a guideline than a rule.
