Every time I go to USH it makes me want to go to USF, it's depressing lol.
I doubt you'll see another park in Hollywood though. The studio would complain about noise control. I wish they'd leave the studio and move the park elsewhere, preferably on flat land. Those escalators are a real pain in the a** lol.
If the ONLY reason you go to USH is for the studio tour that's pretty sad on USH's part lol
