My FH and I are having a casual style backyard wedding this October for approx 130 people. We are having a pizza food truck and a caterer do a buffet of "fair foods" like sliders, lobster rolls, baked potatoes, etc. Our initial plan was to do "cafeteria style" seating since dinner is casual and not everyone has to sit at the same time. (We're also not doing entrances, speeches, or any of that, so no need to all face a stage or whatever). My mother is very upset and feels this will be extremely chaotic with no seating plan. She says people expect assigned seating at a wedding. My FH is very pro-cafeteria style. Now I'm on the fence! On the one hand, I want a more casual feel and think grown adults can find seats. On the other hand, it's a lot of people and I worry about certain folks who don't know each other finding a seat. Opinions and experiences much appreciated!!
