Heard from whom?I've heard Disney isn't happy with the loss of control of the RCID assets, and much of this money is going to go towards acquisition of the RCID assets that Disney has deemed critical to control, such as parking garages, roads, and bridges. Not only do they need to cover the cost of those facilities to acquire them, they also need to budget for the annual property taxes for owning them, as they will no longer be tax exempt. This likely explains all of the increase over their normal expenditures, we aren't getting new lands with this money which is why they didn't announce anything like that.
Because the district is still a district that can float the usual bonds (that are tax exempt for the people who buy them). And with the new contracts in place, Disney tells the District what to do.
