It's a really, really, really, really interesting and believable theory. The thing I find most convincing about it is the fact that there are two doors to the garded and the small green door being on the poor bedroom side makes it seem really real. Really good theory DT!.
I think from look at Kraig's plan I think there
might be access to the poor kitchen/dining/diary room from the poor bedroom? Like this: (hope you don't mind)
I hope they put another ash tray on the rich side so the two teams have to glare at each other and bitch about them while facing them smoking.
