okay this is just my lame brain idea and I agree about not creating another park but this is just me dreaming, heres a brief discription:
Disney's LAND OF LEGENDS It would be a park based on stories and legends, books and myths etc. To access the park you must enter a cave and inside you board a large boat (friendship boat style capacity) as you journey through this mythical mountain (the parks icon) some sort of very impressive effects bring us into an ancient world which materializes around you...(there will be a naration explaining whats happening by some higer power) you are welcomed by the opening of two huge twinkiling bronse doors and into a huge domed palace based on Disney's own made-up anceint civlization where guest services, ticket windows etc would be. You disembark from your boat and walk through the turnstyles and into a thriving lush version of this ancient but modern civilization (think Atlantis with me) this would be your "mainstreet USA" which you will access the rest of the park through. In the center of the park would be a set of ancient looking Portals which would be themed to the land which you are entering (ala nightmare before christmas) which you would access each "land" though Lands might include:
Hometown, State Of Mind: looks like your average modern american hometown, but has attractions based on extraordinary things that might happen in hometown settings like a Sleepy Hollow dark ride, a James and the giant Peach dark ride, New Version of Alien Encounter, some carnival type rides, (and if Disney could get the rights) a tour of The Wonka Chocolate Factory by boat or great glass elevator. A town house/villa style hotel would be located here with each parts facade looking like a different buisness of the town (inside the park).
Frostopia: a land completely indoors where it is very cold and it snows... themed like a mythical snow kingdom... there would be an extesive interactive snow/ ice playground as well as a boat ride themed about the royal family of this monarchy and saving the kingdom from being "melted" by a villain of some sort... you could be protected by some sort of Snow goddess of something... ive seen ideas for something roughly simillar. imagine a quaint winter village with a christmas shop and coffee house.
Mysterious Isle: Land themed as a mythic victorian Scientists settlement placed mysteriously in a remote jungle with rides based on jules verne/H. G. wells type novels (Journey To The Center Of The Earth, updated 20,000 Leageus, Rocket to the moon, and most importantly, The Time Machine... based on the victorian invention which will send guests to H.G. Wells frightening Future) A fantastic highly themed bold Victorian hotel would also be located here inside the park (much different from gland floridian, focuses on the bold dream-like victorian) .
The Fatastic Kingdom: a place far off in the imaginaton of children of years gone by, unicorns are found on grassy planes, friendly animitronic dragons walk the streets, there are detailed mazes to explore, one section of this land would be Alice's Wonderland where there would be a Alice dark ride/walk through maze and a concert of singng flowers.
Dark Dominion: you have mistakened upon the villains land... here everything has a dark but elegant feal that comes with so many villains but reaks of distruction. A ride involving all the villains would be appropriate, where you have been trapped inside their lair and the heroes end up coming to save you.
too far out? I dunno, but tell me what you think
