At this stage, I would say that approximately 50% of the buildings have complete interior and decor, even though most of it are there only for the looks. When the map is done, all of the buildings will be completely decorated at the inside, but not all of it will be accessible for the tributes. Our experience is that single doors leading to small rooms with only decoration in them can only lead to distraction, which makes the game more about finding stuff and searching through rooms than actually playing, especially when you haven't played the map before. That's only our experience and we're more than open for opinions!
