As of right now, the Pixar Play Parade is on the Disneyland.com schedule beginning Friday, March 14 at 5:15. It will run daily at that time for the following 2 weeks, which is peak Spring Break time. Naturally, things could change, but hopefully they won't!
I *think* this parade will have a show stop.. I do know during the summer (or all the time, just toned down when it's cold) there is supposed to be water used in the parade with designated "wet zones" along the route. Similar to what the do over in Hong Kong.
