They're kinda clinical and not really intended for conversational use, but at least they're unique. When in doubt, include a link to the floorplan on the wiki! For example, the spaces above the corner entrance are marked "DEN & BDRM", "BDRM [1]" and "BDRM [2]", and the spaces between the ballroom and the cafe are labeled "STORAGE [1]" (the one with the windows, that Backspace wants to use) and "STORAGE [2]" (no windows - possible the "bunker"?)
A while back, there was talk about some WG coming up with better names for all the spaces, but I'm not sure anything materialized out of that. If there is a better set of names (like "bunker room" and "eyeball room"), please put them up on the wiki somewhere, so we can avoid this kind of confusion.
