Layouts/Floorplans of Funhouses/Walkthrough attractions?

[READYdot]

Hello!

 

I'm an art-teacher here in Luxembourg, Europe and I have this architecture class. There's a lot of boring things I could do with my students, but we decided to do fun things. So their next project will be designing a Funhouse/Walkthrough attraction (their first was themeing a roller coaster gate/portal). But to give them some ideas about how a funhouse/walkthrough attraction is built and how the path the visitors take is only the small part of the attraction I wanted to give them some references of floorplans/layouts of these attractions. Does anyone have some images he'd like to share? Thanks in advance!
