@Jrb1979 @phillip9698 I think you may be misunderstanding my point. I'm not saying this technology doesn't exist or isn't used. I'm a pretty big coaster tech fan - as much as I am a theme park fan. I'm not saying there isn't use for these ideas. I'm saying Disney's use case is very different than the vast majority of the industry. Vekoma's rotation system was developed to solve problems the original Flying Dutchman load system had. The original process took a long time, created reliability issues with the recline system and had poor feedback on comfort. The rotating position change helped address many of those, and that's what we have with F.L.Y. Similarly, the train locking system appears on the Tilt Coaster, as Siren's Curse shows is (finally) being purchased by major players (ignoring COTALand/Circuit Breaker for now).
I'm not trying to say there isn't utility in these features. Quite the contrary. I'm saying Disney (and at times other parks, though not usually) often adds much more complexity to a ride simply for gimmick and story. It's a very cool display of what could be done - and how creative a company like Vekoma can be with its customers. It also isn't actually that practical for most parks. They simply don't need the gimmicks to tell stories, and the extra spend on both the front end and for maintenance (plus reliability risk) isn't worth it for them. They want features that enhance the ride experience itself. An elevator lift with rotating seats looks kinda cool. But, it won't bring in crowds itself, and it doesn't solve any load or lift problems (and may actually create some problems). It just feels gimmicky. However, put it in the context of recreating the door lift in Monsters Inc. - and it now becomes an actual draw in the context of a Disney Park.
Now, if we start to see more parks designing attractions like F.L.Y., Arthur, etc., that would change my argument.
