Nonsense. This isn't a subjective question of which has more international popularity. It's an objective calculation of the actual number of people in the park, the actual number of people who want to ride a given ride.
You really think the demand for Jungle Cruise is "on another planet" from the demand for Universal Rides?
Universal Studios Florida and Islands of Adventure have roughly the same historical annual attendance as Disney Hollywood Studios and slightly higher attendance than Disney California Adventure.
The MK...is the moon compared to them. And yes i do believe JC has the demand because the park as it stands is amazingly underbuilt for annual attendance. Long before covid the MK is a cluster of stagnation.
