Some of the greatest gems in Disney's theme parks are not so easily seen or known. A term given to these treasures is "sleeper" attractions. We talk about what this term means, share an example from Epcot's Cranium Command, and then set sail across the globe to see examples of great "sleeper" attractions in Disneyland Paris, Hong Kong Disneyland, Shanghai Disney, and Tokyo Disney Resort. You may have never heard about these attractions before, but once you become familiar with them, you may never want to visit these parks without checking them out.
