Did you guys see what I said about the Prison rooms? >.>
Yes! And I agree. Besides, not every inmate can survive in the same cell. Some of 'em have special needs (I wouldn't recommend putting a window with lots of wonderful daylight in Rose's room, for example), and describing every single cell would just be too much excessice work on your part.
Your idea of everyone designing their own room, if ever even necessary in the story, sounds great!
