It looks like King Ludwig II of Bavaria created the Disney experience before Walt stumbled on to it. Ludwig created a Fantasyland based on the works of Richard Wagner in the Alps of Bavaria. The Neuschwanstein castle was completely designed to bring the operas come alive. One of the rooms of the castle was a replica of a cave including Stalactites. He wanted an entire floor designed in the Moorish tradition. At the Linderhof Palace he recreated the Blue Grotto and built a moat that included Swan Boats from the Swan King story. He loved the concept of World Fairs and purchased some of the items from fairs that he attended.
For his work in bringing fantasy to life, a group of his government had him declared insane and then promptly had him drowned in a lake along with his doctor.
Walt Disney clearly borrowed a lot of his ideas and took the concept much further. Disney also had a much better fate.
Also, the medieval city of Rothenberg is clearly the model for the Germany Pavilion in Epoct. This little Bavarian tourist town has all the elements of the Epcot version.
