We're having around 160 people at our wedding, which ends up being 20 tables at the venue. Here's the issue: My mom, dad and the caterer all think that we should have open seating. I'm concerned with this plan because I've read on here that you need to have extra seats, but we don't really have extra room in the venue for more tables. My mom says that people will just figure it out and that we're all friends (i.e., that we don't need to add extra tables). None of the family weddings I've been to have had assigned seating/tables and my mom thinks it makes it too formal.
Our walkthrough at the venue s this afternoon and now I'm not sure what to do. WWYD? Do you have a preference for seating types?
