This would be a nightmare scenario for Disney. Do people honestly believe that Disney cares nothing about the quality of the guests' experience? I understand that sites like these are rife with disappointed guests criticizing Disney for becoming increasingly expensive and less like the Disney of old, but it seems odd to suggest that Disney would be happy with a system that leaves their guests with nothing to do but eat and shop in the parks.
I've been going to WDW for decades, and I agree that the current management is vastly different from what it was years ago. I keep watching for the death spiral, where the company raises prices to the extent that fewer people go, leading them to again raise prices which in turn leads to even fewer people, etc. I'll admit that I'm concerned about the Disney company's continued commitment to its parks. I saw what happened when a gorgeous theme park modeled after Disney, Marriott's Great America, was sold to Six Flags.
Whatever happens with Disney will likely be the result of market forces; when the product is no longer of value to a sufficient number of guests, things will change. From what I'm seeing, this is still a long way off (others may disagree). Disney is making a number of decisions that are taking it away from what it used to be, but guests going for the first time likely don't know that and probably don't care. All they know is the kind of experience they will have at the parks - and if it's just shopping and dining with all the good rides gone by noon even with a paid system, they won't be back. If Disney truly doesn't care, the parks will be history before very long.
