Studios is in an especially weird spot because it just doesn’t have enough space. They really need to stop increasing its capacity.
Going from North to South, Tower’s been getting increasingly unreliable (it’s been running on half capacity so frequently how it’s not even funny), but at full cap it’s currently established extended queue lasts about 80 min.
RnRc’s recent downtime didn’t help anything, but for the most part it’s been one of the park’s best case scenarios, with its max line being just shy of an hour.
MMRR was already addressed.
TSM has the blessing of Pixar Place to fill queue (still tops out at ~30-40 min.
Slinky, when stretched to Animation Courtyard, is usually just over one hour.
Aliens can’t get higher than 20 min before they cap the line to let it die down.
Falcon’s extended queue plan is absolutely crazy (it can go all the way to Grand Ave), but even that is only about 90-100 min. (By TSL is just over 1 hr).
Finally, Star Tours is 30 minutes once it’s on Grand Ave.
They are just in a really bad situation, and DAK also struggles with Kilimanjaro and Everest (their actual queues even when using FotLK and Nemo, respectively), not being able to hold more than 30 min.
