I know flat rides are hard to get excited for in general, but they’re so cheap to build (for anyone that isn’t Disney) and I really feel they should add a few to add some additional experiences in a park that’s lacking in many areas.
The spinner in Simpsons Land queue shows the demand for this sort of experience
I was also amazed that Disney didn’t add some additional capacity to Toy Story Land with some more flats. They seem to have done this better at DCA filling in more available space on the pier and surrounding areas with rides.
