So our guest list keeps getting bigger. I have a huge family(my parents have 9 and 7 siblings), FI's Dad has 13 siblings. So our intial count was about 250. Now with everything we're closer to 300. Our venue says it'll hold 450, but thats with tables on the dance floor, and I'd like to avoid taking someones table down after dinner. So we have figured that without putting tables on the dance floor we can seat about 250 people(I'm honestly not sure how they'd fit 450, maybe banquet tables insetad of round). What I've read says to expect 30% declines, so we should be good. But with such a large guest list and not wanting to have too many extra tables on the dance floor the venue really recommends doing a seating chart. I've never been to a wedding that had a seating chart honestly. Thoughts? Seems crazy intimidating trying to seat that many people trying to keep everyone happy.
