I think that maybe you've equated
DVC (Disney Vacation Club) with DC (Disney Club). DVC is a vacation time share. I know that there are some discounts associated with it but I think that you mean DC. There are a number of discounts on hotels that you can take advantage of with that. I'm not a DC member so I can really tell you much more.
Here is a link to get more info on DC.

If I'm the one confused and you are really interested in DVC, I'm sorry. Posts your questions here and there are a lot of people that can help. For DC questions, I'm sure there are people on this board but also on the Resort Board that will know a lot about DC.
