They don't ascribe a budget, let's say, for $100M, and then in the middle of construction slash it to $50 and tell WDW to deal with it.On the cheap is how Disney does everything nowadays. Even the projects that were clearly very expensive has things about it that make it clear there was some cost-cutting or wasted funds.
They *think* it will cost $100M. Allocate $100M. And then start to build what they hope will be only $100M. But when cost overruns occur, then they have to reduce scope to stay in budget.
WDI still gets $100M and are told to deal with it. So they "cut corners." But not because they're clawing back allocated funds, but because the project costs more than they projected.
That's not "cheap." TWDC is allocating $17B for WDW. It isn't being cut. It just may not be enough to build everything they were hoping for.
They're not stingy, they're profligate.
