The big event of the Disneyland Resort's holiday season is the all-new holiday version of World of Color, "Winter Dreams." Hosted by Olaf, the Snowman from the upcoming film "Frozen," it's an extravaganza of light, and music and water. Starting off with a virtual choir made up of hundreds of guests who recorded themselves singing "Glow" with their webcams, it includes scenes from "Bambi," "Secret of the Wings," and a production of "Nutcracker," starring the Toy Story gang.
