What if:
The Jungle Cruise movie tanking at the box office seals the fate of WDW's Jungle Cruise?!
Does that not sound like something they'd consider? MK could use the land. I'm certain it has been discussed internally, at least in the past. With a new movie on the horizon it makes you wonder what they have planned for WDW's Jungle Cruise and if demoing is one of the options on the table; especially if they already have a few replacements in mind. I don't think it'd happen. But...
They don't have enough money in the budget to build a theater they announced. They can't decide what to replace SGE with.
You can be sure Jungle Cruise the ride is safe for, at least, the next five years.
