Have you been to Disney World? I think you could do it. Start out at CA Adventure and focus on CarsLand (you could easily spend all day here, but you don't have that kind of time). Take advantage of the single rider line to get a couple of laps in on Radiator Springs Racers with a short wait (it's worth more than one ride). And then just wander around and enjoy the theming. CarsLand is some of Disney's best work.
Tower of Terror at DL has been converted to a Guarduans of the Galaxy theme. I thought it was meh. Soarin' has a different video, but the experience is pretty much the sane as EPCOT. Toy Story Midway Mania also about the same. The raft ride with the national park them (grizzly something) is supposed to be a lot better than the raft ride at Animal Kingdom, but we skipped it because we didn't want to be all wet.
After CarsLand, head over to MK. Pirates of the Caribbean and the Haunted Mansion are different enough that they are worth a ride. I didn't care for the Matterhorn (too jerky), but it's another oroginal that's with a ride. Space Mountain is different from WDW, and there are some nostalgic dark rides that are fun (Alice in Wonderland, Mr Toad's Wild Ride). I also enjoyed It's a Small World, the storybook boats, and the 20,000 Leagues conversion to Finding Nemo. I'm not sure if Thunder Mountain is the same or different because it was closed for refurbishment, but it's always worth a ride. Indiana Jones is also a unique ride and fun experience that's not at WDW.
Sleepy Beauty Castle is underwhelming in scale, but there is a walk through that is cute. I appreciated it as being the OG of Disney and Walt's vision.
Then head back to CA for the Colors of Wonder show. If you're there at a busy time, you'll want to pick up a fast pass first thing in the morning so that you get a decent viewing spot.
