So the plan is to go to Disney on the 24th.
I only have two things on my list: World of Color and Soarin. Maybe Fantasmic.
Any other suggestions?
LOL, yeah, don't go.
I made the mistake of going to the parks the day before Christmas a few years ago, it was the WORST experience at a Disney park I have ever had. Disneyland was wall to wall people. Everything in the park had at least a 30+ min wait.
If you plan on seeing the Holiday version of World of Color, make sure you get to DCA at opening and get a Fastpass right away. It will sell out quick due to the crowd levels.
Also, take full advantage of Fastpass! You can get more than one FP during the day. You can hold a FP for an attraction for DCA and Disneyland simultaneously. There are a few attractions at the Resort that are disconnected from the FP network in their respected parks. This means the attractions that are disconnected do not talk to the other FP attractions, thus you are not restricted from immediately going and getting another FP for another attraction after you received an FP at a disconnected attraction. Another tip, ALWAYS read your FP ticket to see when you can receive another FP.
Disconnected FP Attractions
DCA:
Radiator Springs Racers
World of Color
California Screamin
Disneyland:
Rodger Rabbits Cartoon Spin
If you are good, you could hold an FP for the following all at the same time:
Radiator Springs Racers
World of Color
California Screamin
And one of the following: Soarin, Grizzly River Run, Goofys Sky School, and Tower of Terror.
And any Disneyland attraction.
And don't forget the Single Rider lines at:
Indiana Jones
Matterhorn
Splash Mountain
Radiator Springs Racers
Soarin
Goofy's Sky School
California Screamin
Grizzly River Run
