I know you don't want to give details here, but what general type of product is it? I mean, is it a physical item Disney could incorporate into their parks, or a service they could provide, or a product people might buy before they visit Disney?
I think your path is easier if it's a product. If so, skip talking to Disney and investigate manufacturing it yourself. Shark Tank, maybe?
Without knowing details, consider that if it's Disney park-appropriate, it'd also be workable for other theme parks -- and other parks don't have Disney's cutthroat attitude towards things like this. Every if you're a Disney fan, consider Busch Gardens or Six Flags or whatever other place.
Keep that detail to yourself. It kind sounds like, "I need money, so feel free to lowball me."
A patent is an excellent idea.
