In my high school, our director just sits in a seat in the
house, usually behind the audience. Our booth is about 7'x12', and then the sound system and light board is up there with two light board operators. It also tends to get hot up there if there is more than two people up there even if the glass isn't in the window of the booth overlooking the
FOH/stage.
Director likes to watch the show and if she has to get a hold of a tech over headset, she walks over to the sound board.
In a way, the booth is a pain in the ass because it is located on the second floor of the school, so you have to completely exit the the theater to go upstairs and into the booth. Makes a long trip when moving equipment between the two.
Plus we've apparently had bad experiences with couches in the booth, years before I got to the school.
