I think theme parks and museums would be revolutionized with the use of Hololens. Historic mansions and castles could produce reenactments to be displayed in specific locations, show before and after images of rooms, or even provide a virtual tour guide. Imagine a haunted house with virtual ghosts with eerie sounds, or a laser tag game with virtual zombies. The Verge mentioned Disney World, and how it would enhance theme parks. All of these establishments usher patrons through confined spaces that should make it fairly easy to create convincing, and repeatable experiences.
