Audio problems and unscheduled show stops during the official premiere of Disney’s Once Upon a Dream Parade, for the 15th Anniversary of Disneyland Resort Paris.

The audio of this parade is so complex they didn’t want to take any chances – and cut all float loops to sync directly with Town Square where the cameras and VIps were watching, to make 100% sure the parade went perfect for these press and invited guests.

Unfortunately, it meant a “once upon a nightmare” for performers and guests watching from elsewhere.
