My wish would be for something as audacious as Disneysea or Epcot were on opening, but I'd be happy with something that lies in-between that kind of more 'out there' truly-unique theme-park planning and something more traditional like Magic Kingdom or IOA. As long as it's beautiful and full of attention and details, because that is what's going to be needed.
It won't happen, but imagine if they were ballsy enough to create a truly Non-IP park?! Oh my!
Why not dream for the stars people!
