I doubt too many people that do not buy into the Contemporary DVC would get a chance to stay there.
Something to think of......back in the 1980's, Marriott was the first to segment their hotels....creating Courtyard, Fairfield Inn, and buying Residence Inn, to target certain segments and pricepoints that were not directly targeted by the traditional Marriott Hotel.
As Marriott is a leader in Vacation Ownership, they have now diversified this product too, creating Horizon's (lower priced and targeted at younger families...which costs about $12K for a lifetime membership), Standard MVC (which is about $20K), Ritz Carlton Club (which is about $50-80K) and Grand Residence ($250K+, but is a "second home" offering, allowing you to own a full year, or just a "season").
Disney could be looking to diversify too, offering a "higher-end" DVC that would be a step above in price, service, and product compared to the other DVC resorts.
Many people would pay extra for the location premium at the Contemporary.
