We haven't done the specific experiences that you're considering, but we did do Keys to the Kingdom at Magic Kingdom and it was awesome! Highly recommended!! At the time, this tour included front-of-the-line access to Jungle Cruise, Pirates (I think), and Haunted Mansion. Lunch was included as was a bottle of water and a commemorative pin. We toured the backstage areas where we saw parade floats, headless characters, & the utilidors and we talked about the symbolism on Main Street and in Liberty Square.
We've also done Undiscovered Future World which was a very cool tour with much more technical detail, but less pretty and magical than KTTK. This one included front-of-the-line access for soarin' and spaceship earth. We also saw behind the scenes at the aquarium (including a VIP lounge), the 3-D glasses cleaning center, Universe of Energy, Test Track, and the IllumiNations barges. No water included, but we did get 20% off at Nine Dragons for lunch, preferred viewing for IllumiNations, and a pin.
We did both tours in April 2012 and I would do both again.
