Using a generous 5 lands- I’d think only a max of 2 could be single IP focus. Maybe even just one.
LoTR would be the obvious best choice with Star Trek or Jurassic World coming in second.
-Europe (say, France?) w/ A FB ride- but not FB only. It would need an original attraction as well or a restaurant, or live entertainment, etc.
-Either Illumination or Dreamworks- not both- with mini-lands. A mashup not single IP
-Nintendo- again, a mashup
And there’s your park.
And personally, I’d rather them have a monsters area and drop the 2nd dedicated IP land (sorry Star Trek or JW).
I don’t think the GP is going to want to go to a park with LoTR, Jurassic World, Hyrule, Far Far and Away, and Forbidden Beast land- and that’s all that’s there is- with no potential for Universal to shoehorn in temporary attractions or characters.
I want all of them- fully immersive and dedicated lands for LoTR, Star Trek, Hyrule, Jurassic World and even Far Far and Away. But the reality is, pick two.
