large Venue. small number of Guests.

This has disaster written all over it. Unless you can contact the no replies yourself, you have a decision to make. If they do show up, will you send them away? You won't have enough food for them. Or, will you order extra food on the off chance that they, or a portion of them, show up?

I really love your venue! I would put one or two less people at each table, space the tables apart a little but further..... maybe have a slightly larger dance area. I have some tables with pictures, a table for the guest book (equivalent), a candy buffet table, cake / groom's cake table, a photo booth with table, the DJ set up area. All of which takes up space.

Why can't you and/or FH make the phone calls to the non-responders? Don't rely on other people To do your work for you.

I think 70-90 people would be great for that space! My cousin got married in a building in PA that looks exactly like that, definitely just as big, and they had about 80 guests. The space was nice and airy with plenty of room, and certainly didn't look bare. If you have enough tables for 70 in that space, DJ, cake, food, etc. it will fill up much more than you can imagine.

Also, our couples shower hosted less than 30 in a space meant for 200. I was nervous that it would be too much space, but it ended up being absolutely perfect. I wouldn't stress about the overabundance of space, it'll be gorgeous!!!

Your venue is beautiful! I would add long tables instead of round and/or a lounge area.

I would suggest putting a 90 degree turn on your reception layout.

Instead of what would normally be considered the "front of the room", make that the side.

I had a gathering of 23 people in a room that held 75, that was the solution to making it feel not so empty. The tables were spaced out so that there was plenty of room for mingling and getting between the tables.

Hwy i love the place you gonna get married or you marry

I love this idea, Melissa! Very unique.

Maybe put up a few extra haystacks as a photo area too? A photo booth might feel too small/constricting, but an open area with hay and/or other decor/props would be so fun for people to take selfies or the photographer to take some guest photos!

I agree with this too. More tables of 6-7 guests would be better than packing in 10 guests at a table.

Oh! If you're having a cocktail hour, you could set up the bar with several tall cocktail tables (no chairs) to make that the "bar zone" which will also take up some space. A cheap votive candle with flameless tea light on each table will be fine for decor.

Also, can you pull any tables (dessert, appetizer, cake, gift) into the room more instead of pushing them against the side walls like in those photos? I would cluster more things in the middle of the room, just don't push anything to the walls if you can avoid it. Our outdoor winery patio venue was HUGE for a reception of only 50 guests, so we made the focus the band/dance floor. We put 6 short cocktail tables/chairs around the dance floor, 6 large dining tables behind those, then 4 high cocktail tables (no chairs) behind the dining tables close to the bar. The whole area was kind of far from the entrance, but by clustering everything together it felt much more intimate.

Your venue is beautiful and it feels intimate because of the wood and architecture! You'll be fine.

I suggest karaoke
