My idea of a park based on Legendary Kingdoms developed in the expansion thread and I'll put my further thoughts on it in here.
Universal's Legendary Kingdoms (or if there's a better name I'll go with that)
The lands would be Hyrule, Rivendelle, and Transylvania for those based on existing IP. For original concepts I thought it would be cool to take lost kingdoms from around the world. Atlantis would of course have to be included and then
@quinnmac000 suggested the Chinese Empire and my thoughts went to Shangri La. Then I thought of the Mayan/Aztec Empire and, of course, El Dorado. Imagine, a whole land made to look like it's made of gold. Thoughts?
