I was just daydreaming what I'd do if I was CEO/head of Parks and Resorts so thought I'd post my ideas here.
My number one instruction to WDI would be to come up with a reimagined EPCOT Center, give Future World meaning, and anchor it with a new Horizons E-ticket ride.
This would be the big draw of the park, an immersive high tech ride where you ride through next-gen suspended omnimovers, pods that can move in all directions, (maybe with something similar to kuka arms?) plunging you down into the ocean or soaring you up into space, mixing screens, animatronics, and holograms to really give Future World a reason for its name.
I'd gut Innoventions, rename it Communicore and have it as a permanent E3 type expo for Samsung, Apple, Google, Microsoft, Oculus, LG etc. to show off their latest products, and let customers play with stuff not yet on the shelves.
The phase 2 would be to redo Universe of Energy, give it a new movie, restore broken effects like the curtain and add some animatronics... possibly shorten it if possible to tighten the thing up and make it fresh.
Imagination would also get some love, probably with a completely new ride using the same system.
In World Showcase I'd add two new countries - Brazil and India. They'd have great photo-ops, wonderful food, and possibly movies or stage shows.
I think the total cost of my Epcot reworking would be about 750M, less than the DCA redo and less than half what MyMagic cost.
DHS can have the Star Wars/Pixar things probably already planned, but I'd also add a spinner ride in Animation Courtyard (probably moving the Carpets from Adventureland) and I'd reinvent Animation as a true behind the scenes, hands-on experience where users get to see themselves as CGI characters and learn all the steps that go into making a modern animated film.
Magic Kingdom would be less of a priority, my main thing here would be to ensure maintenance is kept up. I'd eventually get rid of Stitch and retheme Tomorrowland, but for the most part I'd leave it alone at first.
Animal Kingdom would see a minor retheme of Chester and Hesters, giving it closer ties to the Institute. I'd add a section for Australian animals, and a land for fictional animals which basically will be a boat ride or omnimover with unicorns, dragons, sphinxes and all manner of creatures coming to life via animatronics.
Finally, I'd rework Disney Springs to once again be a nightlife district after 10PM, seeing what I could do to restore the spirit of Pleasure Island and make it a destination for locals once again.
Total budget for all my changes, around 2.5 billion I think, so for half the cost of what they paid for Lucasfilm, or a not much more than MyMagic cost, they could reinvent WDW as a world-class destination and once again be top of the class in every area.
