You might've liked the now-closed themed Hotel Valdivia in Santiago:

My now-wife and I stayed there almost 20 years ago, in the disco room: spa and waterfall, shower in an orange glass hexagon, a toilet room surrounded by mirrors. It was quite the experience.
On theme parks, I wonder if there's ever been research into serious fans of them, and if they have formative history in common, like first visiting one at a key age, or similar. I can appreciate the experience, but I'm personally baffled by people who just keep returning to the exclusion of other opportunities around the country or world. Each to their own though!
