Ideally, if poker could be played in the next room.
Since that's not possible, we should take the largest conference room so that the poker players aren't right next to the other players. I think a large night bar would be perfect, as long as there aren't any outsiders there.
How far is it from the conference room? If it's too far, it will create a separation between the two groups, which wouldn't be ideal.
The house is not far from the hall, maybe about 100-150 meters. The entire standard hotel rooms are located there, but the cottages and houses are a bit further away.
