What kind of discounts are you really looking for? We already paid for our rooms at a price that doesn't go up... so when rooms are at premium prices you are getting a much better deal. Disney has no incentive to give free dining for pre-paid rooms... Besides, if you do the math and rent the points out that you would have used and booked cash for the specials, rarely do you get a better deal for equivalent rooms. I checked during the 4 for 7 deal and DVC points was the best way to go unless I wanted a "lesser" room at a moderate instead of a room at BLT or BCV or BWV. Since I'd rather have the nicer room, it was a no brainer for me.
They have cut and added perks... ultimately, I love the fact that we get such a deep discount on the APs. This is something that disney doesn't have to do, although it is smart business as it helps get DVCers down more often.
Would I love to see DIsney change some things? Sure... A loyalty points program for all Disney customers would be fantastic... points for passes, hotel stays, DVC purchases, etc. I think Disney is extremely shortsighted in not doing this, but I'm not running the show (although my ego and fantasies tell me I'd run it better than the people running it now...

) so its not my call. I'd love for Disney to reign in the ticket increases... yes it does bother me that Disney has doubled Single day tickets in price since 1998, while it took double that team to reach that level before. It really bothers me when many of the new rides lack the innovation that the old ones did and could be so much better.
But that doesn't mean I think they should discount me because I'm DVC. I, like many others, just feel the product is not nearly as good as it used to be, even if I still enjoy it. And ultimately, I'm part of the problem because, despite all the garbage Disney does lately, I still go back and give them my money. THey have no reason to change until a large majority force change. Which I doubt will happen.
