Venue with two separate rooms?

I went to a wedding once at a venue that had a bunch of different rooms. The dinner was downstairs, then everyone moved upstairs for dancing. It was fine. They put a few tables along the side of the dance floor, and there was seating in other smaller rooms on that floor as well for people who wanted to have more private or quiet chats. It's was a museum type of place, so guests were also free to walk around and look at exhibits, etc. I thought it was fine.

I actually went to a wedding recently where they started in one location and moved us to another to finish the night. While it was awkward, it wasn't a big deal. At least everyone was in the same room at the same time.

How are the rooms connected?

It may be awkward if they are separated by a hall, but like PP have said, I would line the dance floor with tables so people can still sit and chat if they want.

I don't think it will be too big of a deal as long as there is a secure place for people to put any belongings they might have brought with them. Your date is in October, and depending on where you live your guests may have coats.

I went to a wedding like this. We stayed in the dance room for first/parent dances, then got shuffled into the dinner space, and then went back over for the dance space. I would recommend a few tables (maybe high top tables) and a couple chairs in the dancing area in case people want to hang there but not dance. But it was fine. Are they open/connected or are they two very separate rooms?

As long as you can seat everyone in the same room for the meal, it's fine.

I was at a wedding in one of these old stately houses. The drinks reception used the hallway/ lobby ( big and wide) , sitting rooms and outside area. The speeches were done in the lobby with the couple and bridal party standing on the bottom steps of the stairs. The guests were split into two rooms for the meal it worked well. this wasn't normal there, nor the couples fault. Thier original venue closed down 6 days before the wedding, venues in the area were hard to find and this place said they would work around thier numbers (normally they didn't do as big a wedding). After the meal we all moved to the other side of the house where a room was set up for dancing. They had some chairs and tables set up for people to sit and watch too. Also there were are few other areas that guests were free to wander in and sit down if they didn't like the music. It was honestly one of the best weddings I've been too. Guests were looked after so well and no one mined moveing about . It actually worked out really well.

I've been to a wedding like that before and it was fine. Like PPs said, set up some high tops and chairs in the room with the dance floor. Maybe even a lounge area with a couch and some arm chairs if possible

A lot of estate weddings have cocktail hour, ceremony and dinner in separate rooms, but I've never seen dinner & dancing in separate rooms. I would do as other PP's said and have chairs and tables in the reception room and it could work. People definitely need a place to sit and take a break and you don't want them to have to sit in a different room.
