Since
@ParentsOf4 and others have given the financial answers to the question, I would like to follow up with I believe to an example of the cosmetic, wal-mart style "dumb down" you get with DVC. Lets compare the original Grand Floridian with its DVC counterpart. Here is a picture of the original Grand Floridian. Its marvelous, exquisite, and extremely detail oriented. It is their "flagship resort", as they like to call it.

Now, lets take a look at the DVC version. I have placed arrows in areas that show the extreme LACK of detail when compared to the original GF design. Please keep in mind that this building is an addition to the most expensive and what Disney calls their "flagship resort". Also keep in mind the original was built decades ago when the compnay had less money to work with and technology and materials were not as advanced as today.

Lets go from top to bottom. Look at the spires on the DVC building. No windows, no layered roofing effect and much smaller. Also notice the roof is flat on DVC compared to the original which is layered. Now look at the covered windows on the roof (above the rooms) There isnt even a window on the DVC version, theyre not even sunk in and on the original building there is a window (on the roof) above EVERY room, on the DVC, there is just a few, and again, extremely less detailed. Next we move onto the side of buildings, IMO, the worst part. What were they thinking? Look at the sides of the original building, there are top to bottom bay window style towers with windows and coned rooftops. The side of DVC is just flat and white. They didnt even put faux windows in to create a decent look. Just a wall. It makes it look like a slightly upgraded
Red Roof Inn. Also notice the lack of trees. Theres very few compared to the original and the original has much better landscaping all around the resort, not just near the entrance. I will say that the rooms are excellent in both style and design, but that doesnt make up for the wal marting of the outside. Is this seriously the best they could do? Or is it the cheapest they could do while still maintaining somewhat of a resemblance to the original? I feel bad for all the people staying at the Poly who have to look at Disneys flagship pile of hot, steaming pooh (exterior wise).
