In case you did not understand, I will expand upon the last reply
No, Disney can and will not except ideas in anyway.
This all stems back to the Wide World of Sports lawsuite, where a man clamied they stole his or his fathers, someones ideas when he presented them to Disney, disney clamied that they already had the idea for the sports complex, but the court ruled in the favor the the man that the complex was so similar to the one he proposed that Disney must have borrowed from it( then again how many ways are there to make a sports complex, wouldn't they all look similair, anyways)
Point is to prevent furthere legal problems Disney will not in any way except ideas unless you work for them.
