I used to work in the Training Department at the Disney Reservations Center. One thing we always stressed with our New Hire classes was to not make assumptions about what guests will consider to be affordable. If a guest calls and asks for a Concierge Room with the Deluxe Dining Plan, you should provide the price without qualifications like "I know this is a lot of money..."
For whatever reason, I always was tasked with doing the live call demonstration for those classes. I took guest calls while 15-20 new Cast Members listened. Once, I got a guest asking for the works at Disney's Grand Floridian Resort and Spa. The price was north of $10,000. I was facing all the Cast Members and could see their expressions of doubt. I delivered the price and the woman said, "Sounds good." To this day, I'm certain some people in that room believe the call was staged. I just got very lucky.
I think you both are correct in stating that while this won't be widely used, there is a small market for it.
