In Disney's fiscal 2019, theme parks raked in $26 billion in revenue and $6.7 billion in operating income
On the surface (I say surface, purposefully ignoring the pandemic, shut-down issues, and dumb re-skins they have planned), they could've afforded a new location. This is something that should've been done years ago.
Also, it doesn't need to be another WDW. They could start with 1 or 2 parks, partner up with some hotels, and get to work. I'd also like to add, while Disney thinks everyone wants another ROTR or Smuggler's Run, we all love cheaper Fantasyland attractions too.
