I could think of better space-use for the other rooms. A digital theater, a computer & electronic room etc. A Firearms Room would be awesome, but that NY-Shitty, so that's out-of-the-question.
People who need Vomitoriums wouldn't be on my Cheffing or Party "A-List". While being a Farmer, I'm also a Chef (CIA 80s), so if they ever used one for that, I wouldn't bother with the elevator for them, they'd go out a window. LOL.
