Although Princess Tiana sings about “Blue skies and sunshine, guaranteed” in Mickey’s Soundsational Parade, there’s little that the Disneyland Resort can do when rain falls at the Happiest Place on Earth. As such, when inclement weather prevents the regularly scheduled parade to go on, Disney falls back on a rainy day contingency: Mickey and Friends Cavalcade.
Various characters from the parade are placed into Main Street vehicles where they will be covered from the rain and won’t be at risk from slipping from the wet surfaces… this also helps protect those expensive parade costumes!
Mickey and Friends Cavalcade is much smaller in scale but offers some sort of entertainment for guests when weather does not cooperate with royal decree for guaranteed perfect conditions.
