When the new Disney World attraction Frozen Ever After opened at Epcot Center recently in Orlando, eager families waited in line for up to five hours for their turn to see Anna and Elsa in the animatronic flesh. But sprinkled in amongst the jubilant throngs were some unhappy faces mourning the loss of the ride that the Frozen gang replaced: the Maelstrom, a log flume that had entertained visitors since 1988. It’s a reminder that almost every time a new ride debuts at the Happiest Place on Earth, another one twinkles out of existence. From Phantom Boats and Flying Saucers to a World of Motion and an ExtraTERRORestrial Encounter, we’ve assembled this gallery of some rides that are no longer in operation at Disney World and/or Disneyland in Anaheim.
