There are a couple that are probably still safe to go to. There's lounges - I guess I'll find a room close to one? There's the mess hall. At least that one I can testify is still safe. We've found some other rooms across the Station but most of them haven't been used in so long it seems pointless. I found the remains of a pool in one huge room - a real pool! - but it was empty and the bottom coated in this black stuff and I wasn't going to waste our fresh water supply on that.
