They've done it before, they can do it again. Make the Chinese Theater/GMR the park's icon. It's majestic, it's symbolic of what the park stands for, and it's a fitting centerpiece.
And for those who say the Chinese Theater should not be the park's icon because it isn't a Disney creation, I say this: How much of that entire park is actually based upon Disney creations?
Star Wars?
The Twilight Zone?
Aerosmith?
The Muppets?
Indiana Jones?
Toy Story?
The park is mostly a vast collection of IP's which Disney has either purchased, partnered with, or licensed with over the years. So why is it that important that the icon is something strictly out of the minds of WDI? The Chinese Theater is a magnificent representation of the park's theme of entertainment. It worked before...it can work yet again.
