Same I went to sleep in my captains bed and Sam and Sarah at different times where using it. I’ve also seen all of them sitting at a table presumably “eating” since there was food on the thing. Lastly I periodically see them at select work stations. One of Barrett’s fav spots was in my workshop fiddling with the research console. I’ve also seen Sarah “interact” with the weapons table or sit down at crew stations/consoles around my ship
