I think Disney actually cares about throughput, at least that's my anecdotal observation. I went to Disneyland in September last year, unfortunately it was the first day of Anaheim resident's half price (I didn't find out about this until after) and the park was smashed - my poor friend from Illinois was like "but the crowd calendar said low" lol. I did most things on Lightning Lane, but the ones I didn't, the lines moved really well - Indiana Jones especially take a bow. That's one thing about long lines, it's a lot more bearable if they're constantly moving, it may be a perceptive thing psychologically, but it makes for much less dissatisfaction.
Movie World, speaking as a consumer, does not seem to care; and it's real simple for me: don't go.
