Some figures are dark for a reason, you will never get the full picture from the outside I am afraid. But the debt is a huge burden. The interest rates in the 80's and 90's killed the place, and I remember in 1994, there was actually talk of just closing the place or selling it. I doubt those talks got very far, but it is why we got the attractions we did in the following years instead of the more grand and expensive ones.
We are not just paying the spent costs of building and running the place, but the high interest before. The debts have been restructured before, and they may again, it all helps. But there are not many more props to sell on Ebay, or Malls to sell off under licence.
And Disney have cut quality on their staff training so much, that companies like Marriott and Radisson, that used to use the Disney cleaning and maintanence contracts, got rid of Disney altogether and brought their own people in - mainly due to lack of quality rather than expensive costs.
