Ceremony seating dilemma

Hello,
So the venue I'm doing the reception at charges 1,000 fee just to do the half hour ceremony. We have 5 hours for the whole wedding package we picked. The venue said we don't have to do the ceremony with the setup of chairs etc and that we can just have it diy style with the guests coming and sitting in their seats by the table. The ceremony would be in the same room as the reception. I asked my fiance if it would be weird that everyone looks from their tables while we do the ceremony within that 5hr time slot literally on the dance floor. No chairs. I'm trying to figure out how to make this work. After that a one hour cocktail hour would follow. We are on a budget and think it's ridiculous to pay 1k for a half hour when we can do the vows in the same room. How would this work with guests coming and not making it look tacky? Anyone ever seen this before? Thanks!
