A >small< ship, but still no stars to steer her by

So this isn't JUST me blathering on at the wind, can anyone think of a shipboard location that should be added other than the ones I listed above, engineering, the shuttle bay, and the computer room? A briefing room, I guess - scenes in the Captain's Ready Room are common enough. ...

On a ship this small, you'd be looking at multifunction rooms. A briefing room can be used as a recreation room when briefings aren't being held (you don't need a holodeck to play chess, just a chess set and a place to play), so, yeah, I'd include one.

If you're including a medic in the crew, you might want a sickbay - or at least a dispensary. (Use that briefing/rec room as a makeshift sick ward if necessary.)
