To the bolded, I think Disney has shown recently that they would be more than happy with the exact opposite --- happy to continue along with single digit attendance increases as long as top line rev and profitability hit their targets.
All you have to do is look at their largest WDW Parks investment in years - NextGen. And as they've publicly stated too many times to count - it's focused on farming - getting maximum yield out of the existing footprint and minimal go forward liability and expense. Same thing on the Resorts side, DVC conversion of existing decades-old structures - minimal increase in ongoing ops expense after significant cash upfront
They've shown pretty specifically that they only want attendance up as long as the impact is minimal to the bottom line - headcount, liability, etc., etc.,....
So, whether its Star Wars or anything else in DHS after whatever becomes of Avatar - CapEx for things we want is more than likely going to mean something else is cut or optimized, operationally. They're at 70,000+ employees. The Orlando employee market is only so big.
It's the big gorilla we should photoshop into every expansion rumor that pops up for WDW...
