You guys seriously think Disney is going to be hurting, at some point, because people paid them millions of dollars for hotel rooms months, years, decades in advance? Then, you pay them every year to maintain it for you? Then, later on, they get it all back and get to sell it again?
The original DVC price-point was built around DVC guests being "rich" and effectively spending as much or more than average resort guests. DVC, after all, is targeted at the Deluxe Resort market. For about its first 10 years, Disney gave DVC members free APs, that's how much they valued their business, that's how much they wanted them in the theme parks. Even today, DVC members receive a $150 AP discount.
DVC was intended to be an exclusive "club". However, with the relatively recent construction of SSR, AKV, and BLT, the game has changed. Those 3 resorts added the equivalent of nearly 2400 rooms to the mix. Prior to those 3 resorts, DVC had only about 1700 equivalent rooms. Combined, these numbers now make up an appreciable portion of WDW's total onsite occupancy. DVC is no longer the exclusive club it once was intended to be.
Disney has made a lot of money selling DVC but that money is already on the books. That's profit made in previous years. It doesn't help Disney in future years.
The annual Maintenance Fee (MF) essentially covers cost only; it provides some revenue but very little profit. A company doesn't think simply in terms of revenue; it thinks in terms of profit. From a corporate perspective, I don't care what my revenue is if I'm not making money. I don't operate a private company with the intention of breaking even.
Think of it this way. Looking at just my MF, it costs me
$65/night to stay in a studio at the Boardwalk Villas during the popular Food & Wine Festival. Even with a 30% discount, a comparable room at the Boardwalk Inn is
$336/night for those same nights. The difference between those two numbers closely mirrors how much Disney makes off each stay at a Deluxe Resort per night. That's a huge amount of money; 7 nights in a Deluxe resort is more profitable for Disney than a family of 4 buying 7-day tickets. For someone staying at the Boardwalk Inn, Disney is banking a ton of cash. For someone staying on points at the Boardwalk Villas, Disney is banking essentially 0.
The first DVCs are set to expire in 2042. That's in 29 years. 29 years is an
eternity in business. As the number of DVC resorts expands and take up a larger percentage of WDW onsite guests, how does Disney fill that 29-year gap?
Perhaps worse, in 29 years, DVCs will flood the market. It will take years or even decades for Disney to sell all those points. In the meantime, Disney eats MF at those resorts.
Disney tried selling 15-year extensions at OKW but it flew like a lead balloon. For the next few decades, Disney's going to be facing an increasing problem with its growing number of DVC members if Disney doesn't figure out a way to get those members back into the parks spending money and wanting to extend their contracts. The way to do it is either offer rock-bottom prices (yeah, sure, Disney loves offering lower prices) or to get them back into the parks the same way they get anyone into the parks, by investing in the parks.
