Oh... I'd imagine that guards have a pretty good salary, and that accommodations for them would be quite nice.  Perhaps not as plush as it would be for the Warden of course.  Scientists would probably have it a bit better than the guards - maybe they have small apartments instead of sharing a common area?  Rec facilities and such would, of course, be shared by everyone (except the Warden, perhaps, who might have a few extra benefits?)
