Our house uses a storyline and each room/scene has actors. We use hidden doors that blend into the decor in nearly every room. This seems to make our customers a bit more uneasy not knowing exactly how they are leaving until the actor reveals the exit. It also gives the actor complete control of the time line as well as directing/redirecting them to the scares in each room as we are very animatronic heavy in each scene. The passages that our guests exit into are all pitch dark turn about mazes leading them to the next room. We open throughout the rest of the year for private interactive mystery parties, with very few actors, so this works out very well for us. The layout of the house has all the rooms from the game 'Clue', but we have added a few more like the master bedroom, nursery, wine cellar, etc. Here are pictures of some of the passage doors:
