We are planning 4 days in Disneyland. Yes, we absolutely love Studios in Florida but I heard it is not the same at all. I think we would enjoy Nintendo Land.
I'll go over it real quick. Some thing are the same, and some are sort of deceptively the same.
Universal Hollywood has the following that are the same as USO:
Harry Potter and the Forbidden Journey
Flight of the Hippogriff
The Simpson's Ride
Despicable Me: Minion Mayhem
Transformers: The Ride 3D
The following are unique rides from USO:
Silly Swirly Fun Ride
The Secret Life of Pets: Off the Leash (new and popular - may use virtual queue)
Dreamworks Theater - Kung Fu Panda: The Emporer's Quest (a re-theme of the Shrek 4-D show)
Mario Kart: Bowser's Challenge (obviously super new and hot!)
The following are similar, but not the same:
Revenge of the Mummy - close, but not exactly the same - Note: There are rumors of this closing forever in 2023.
Jurassic World: The Ride - a retheme of the old Jurassic Park River Adventure, but with lots of new effects and scenes
Backlot Tour: Wile the Backlot Tour is unique, you will experience as part of it King Kong 360 3-D which is the main portion of the Skull Island: Reign of Kong (though the Orlando ride has more scenes) and Fast and the Furious: Supercharged, which is esentially the same as the Orlando ride minus the queue.
DO NOT MISS:
Waterworld: A Live Sea War Spectacular. This is
THE BEST theme park stunt show I have ever seen. It's better than the movie too, if that's your worry. Make time to see it - it's worth it!
I hope that is helpful.
