Maybe they are replacing this stuff with new experiences, no one knows yet, to bring new stuff in, you need to remove the old stuff.
That is not how business works.... The FastPass+ and My Disney Experience will have their own separate budget from In park entertainment at Walt Disney World.
If FP+ and
MDE are over budget, that money would not come out of WDW's budget alone. I will bet Disney plans to use FP+ and MDE at every park around the world, so why would WDW's budget be paying for it?
My guess, WDW is removing some of the older, stale experiences, to make room for new experiences in the future. Are we talking about next week future? no, but in a few months, for the summer? yes.
People complain Disney doesn't add anything new, but they also complain when they take stuff out, you can't have both.
