A big thing that still makes a difference with WDW versus
Epic Universe -- and I am very excited to go to EU -- is the transportation options, and while losing Magical Express was a bad move, if they can get a Skyliner expansion ramped up, that keeps WDW folks on property and they don't have to rent a car.
Epic Universe looks amazing, but unless you're staying at Helios for $900 a night (guessing,) you're off site and being bused in down the highway. It's not as immersive as the Disney bubble. If they expand the Skyliner to the neglected/overrun areas, they can build more DVC/hotels, ensure fuller occupancy, and hopefully divert more traffic via hopping to all four parks, instead of MK being overrun. I also can see them extending to MK as a stopgap for the monorail since the infrastructure for it is really showing its age and it needs capacity help -- unless they make monorail usage tied to Magic Bands/guests staying on site versus commuters or something. The new buses they introduced seem to limit
ECV numbers, and it really bogs the loading/unloading process down a lot. The Skyliner is much more efficient pulling those dedicated cars offline to load/unload. With an aging population base, they need MORE ECV access and transportation options, not less.
UO/IOA, granted, we only have gone twice, but I honestly don't remember anyone with strollers, let alone
ECVs and wheelchairs. I did have someone with a service dog for Kong (which blew my mind that the dog was so calm in that noise and chaos!) but WDW is the default park for folks who need some help and the stroller set.
I absolutely could be wrong, but this is honestly my biggest hoped-for announcement -- that actually becomes a reality! So much time is wasted on transportation, and I think a lot of folks tire and bail rather than park hop, so it just becomes MK as the default all the time.
