Really a huge waste of space, BUT, strangely enough it may well end up a huge driver for attendance, maybe more of a driver than Pandora. This is the type of thing that those Disney vacation tourists eat up, and would probably schedule a vacation just to see it.
I see a bigger return on investment for this than trying to recoup the Pandora costs. This is costing way more than it should for what it has, but it's still just costing one fourth of Pandora. Disney will make money on this land, my guess. .....And that's sad, since Pandora will be soooooo much better than this no substance expansion.
