I've seen one that is combined with a small place to sit around independently of visiting a room, where you have a lot of mechanical puzzles available to play around with. It was fun just to stay there and explore those. It's close to the spirit of the room experience itself, and I can imagine going back to just explore those. And the owner can probably add those easier than redesigning the rooms all the time.
