The best move for Disney would be to close the Voyage of the Little Mermaid and Launch Bat, replace the Animation Courtyard archway and replace it with the Monsters University gate, then put in the Monsters Inc. roller coaster where Launch Bay used to be.
Expand that area behind One Man's Dream and connect it into Toy Story Land.
They can have a REAL Pizza Planet and re-theme PizzaRizzo's into something better, and this time with little animatronic muppet rats throughout helping make food, etc.
Then they can have Mike and Sulley with a permanent meet and greet in the Monsters Inc. area.
They can possibly add an Inside Out ride through the mind.
Then they can even add a Wall-E ride where Wall-E and Eve take you on a journey through space with the captain of the ship and they teach you about the environment and health.
Floating overhead they should permanently have the house on balloons from "Up".
And just on the outskirts of Andy's backyard they can put in Al's Toy Barn.
I wouldn't mind if they cut a hole in Andy's fence and you could look into his evil neighbor kid's backyard and see some deformed toys moving around. That would be very fun even as a projection through the eyehole.
There are so many better ways to use this area.
