Yep, grabbing the adjacent space for pitting will make things pretty comfortable for everybody. Two extra toilets and a bunch of room to spread out. It's the unit right next door, so walking to the track from there is actually closer than from the pits in the same room as the track in most cases.
We'll also make sure full audio and video of the racing is available in that space. My intention would be to pipe the audio over, and project video on one of the walls.
