Aside from the 'is that an AI isn't it' question, I'm glad the subject and thread was revived as I missed it first time around, and it's an interesting subject.
I've never thought of a theme park as needing any rides at all, just a solid and well executed theme and some sort of entertainment.
@Furiustobaco gave what would be my first example of a water park that I'd definitely consider to be a theme park. The theme is so well executed that the designer had to seek permission from the Thai Royal family to use it. When you step into the park you feel like you're transcending worlds, leaving the noisy, dusty, hustle and bustle of what is essentially a large desert city, into a lush, Thai, jungle paradise.
But it goes further than water parks for me. Big, well themed festival areas like Glastonbury's Shangri La or Arcadia, Boomtown's Districts or even Tomorrowland are all crazy adult theme parks in my opinion.
If you've never been to any of these festivals google some of the following...
- Glastonbury NYC Downlow (A temporary nightclub in Shangri La themed to a meat factory!)
- Glastonbury The Common (Another part which has a massive temple arena, as well as a secret rave behind a waterfall!)
- Glastonbury Arcadia (Raving under a giant (alien?) metal spider that shoots fire!)
- Glastonbury Unfairground (Think dystopian, rip off, amusement park / fairground, kind of Dismaland-ish, although unfairground came first. Given Banksy's long standing connection with Glastonbury, it does make you wonder if he took some inspiration.)
- Boomtown Old Town
- Boomtown Metropolis
- Tomorrowland (Pretty much all of it!)
Festivals aside there's halloween... I'd consider a large, well themed halloween event, such as Shocktoberfest or Screamfest, to be theme parks.
So yeh, having coasters and rides doesn't necessarily mean you're a theme park, but equally, not having them doesn't mean you aren't. For me, a theme park is a well themed place for having fun, permanent or temporary...
