Piggybacking off of Accelerando & Wkiml;
El Barto, I was a season pass holder at Cedar Point for 6 years. So I did the 200+ foot rides 30 times over at the very least.
While it's unfair to fully compare a Disney Park to the rest (outside of Universal), parks with 100% thrills just cannot really compete. It truly is a full experience like Accelerando said, and not just about how fast this ride is, how scary is it.
The example I will always use is Mission: Space. I cannot really do spinning rides like a Scrambler, Matterhorn, Tilt a Whirl and so on many times over without being nauseous. Mission: Space spins like a Gravitron does… a lot for at least 30 seconds two times. After getting off the ride with my brother, I asked him "when was the ride spinning?" The ride is themed and masked THAT well to me. They pump cool air in, put your face close to a screen and other sly tricks probably to divert your attention away from the fact that you're spinning. Sure, the thrills are not 85mph speeds around 250 foot drops and overbanked turns, but's that not the full point.
When I waited for Top Thrill Dragster at CP on opening day when it was new, I waited 5 hours through switchback after switchback. If I waited for Tower of Terror at WDW (NOTHING to due with the Mouse, or Disney properties btw) for hours, I would wait through an outdoor themed area like Hollywood in the 1920's, go inside a hotel mockup, then a movie room, then an elevator shaft, then finally the ride. Waiting is at times an experience! And the food and lodging is a whole other discussion.
I cannot fully describe honestly why its better, but it is to me as a 31 year old adult male with no kids. Thrilling rides do exist there as Accelerando pointed out, and you can spend your whole time there without ever meeting the Mouse, nor going on a fairytale attraction or to a show (at least at WDW). Disney is now spending $200 million on their top tier rides/attractions… that should dictate just how much they put into rides as a complete experience, from the time one enters the ride line to when they exit. Top end coasters are around $30 million I think.
But I do understand the price thing El Barto, and I think Disney, although the market is still paying their price increases, constantly price vacations further away from what most families can afford. Much like a shrinking middle class, Disney continues to stratify their visitors and push the best experiences closer away from the middle and up into the upper classes.
