Sorin over California is one of the few rides that have not been updated or completly change since California Adventure opened in 2001. Here are some ideas.
The queue: It would mostly stay the same but with updated information and updated pictures.
The Ride: Update everything inside the ride. That includes the sound system and of course but new screens up. The ride scenes would be the same but updated pictures. And in the final scene instead of bieng Disneyland at christmas time. It would be California Adventure during christmas time with the World of Color fountains in the background.
