What they should do with the Castle Suite...
I think Disney should start a backstage tour that costs $$$ that includes a tour of several resort suites, concierge lounges, and a nice lunch somewhere exclusive, like the lounge at Living Seas.
Maybe only make it available to concierge level guests.
And they should donate a portion of the proceeds to Give Kids the World or a similar charity. I think anything they do with the Castle Suite should include a focus on charity.
That's my big idea of the day! :D
