During my humble career at Disney, I have been one of these very VIP tour guides taking around families who are overwhelmed with the large property in Florida and getting them from point A to Point B in an efficient manner while telling them the history of the property. The other sect of people who used this service were film, TV, music and political figures who wanted to experience the Disney parks and retain anonymity.
My heart just sings for the SDC property (having worked there as well!) but not sure how the VIP program would work on the same level. I like the idea of "themed" Citizens taking Guests around while remaining in character and showing them the sights...but since the park is so small, I wonder if people would swallow the $$$ price point to do it.
