Nothing is actually permanent in a theme park, and many hypothetically "permanent" attractions don't last as long as others. Just ask the creators of Superstar Limo, another "permanent" attraction.
None of the currently unused theaters would be appropriate for a Wicked show, unless they retheme all of Lost Continent in the process.
Seriously?
You're really going to go this way with it and pretend like you don't know what I mean?
Fine, we'll say "semi-permanent' or perhaps "long-term" by which I mean,
intended to not be temporary or short-lived.
I would call a takeover of the Hello Kitty store and a green
paint-job that can be changed to any other color in a day or two to likely
not be a semi-permanent/long-term change, for instance - sort of like all the popup tribute stores they do.
I could see that going back to Hello Kitty or being redone for the next big thing Universal wants to promote in late 2026 or early 2027 after the second half has gone through theatrical and home releases.
Or are you saying the show in Japan was intended to be there longer but was a flop which is why it only made it five years?
The Lost Continent theater is right on the edge of that
Island, they'd hardly have to retheme everything to make it work.
It would seem a pretty stupid move both in cost and land to build a fourth theater when they already have three unused.
