I feel like, um, practitioners of various Native American religions might have something to say to that? Also practitioners of imported earth-based traditions like African/Christian syncretic religions and some Neo-Pagan religions, but let's face it, those are only as American as Christianity. (I suppose an argument could be made for the African syncretics being American. Those are kind of the religious equivalent of jazz and the blues.)

The thing that sticks out to me about Disney is that even the smells are controlled and designed. In the Magic Kingdom they waft the artificially-created smell of cookies baking into the air (although to me it smells more like ice cream cones than cookies) because apparently, according to studies, that smell makes many people feel more comfortable and at home, and I guess they want to keep people from being spooked by giant crowds and weird fake architecture. (To be honest, it just makes me hungry for ice cream cones, which is probably also part of their plan.) Almost every single sensory experience you have in a Disney park is according to plan.
