I guess they're mostly conserving power. During the star-system parabolic orbit, they specifically said they were expanding the footprint, i.e. rooms/area. They didn't explicitly say they were looking for more interesting features. Perhaps they have a reasonable floorplan, with labels, within the computer. Saying that, since the location of the observation dome/shuttles implies the gate-room is somewhere at the base of the big tail-fin, I'm fairly sure they've not been too far forward towards the nose of the ship. And you'd think there's a proper "bridge" at 'the pointy end' somewhere... and there's strong implication they've not got direct access to the engine room (internally, at least).
