Who would pay for it, and how? Disney justifies the free DDP because it is filling a cash room that would probably otherwise go empty. If DVC were to off it to members, how would it be funded? More dues? There would be no advantage to Disney Vacation Development or DVC Marketing to fund it...we're already members, we're already paid
The documents you signed at purchase state specifically that it is not an investment, only a pre-paid vacation plan. If you did not agree with that definition, it probably was not a good idea to purchase.
As far as why they don't upgrade DVCers on points, DVC does not own/control the rooms once they have been turned over to cash inventory. How is it fair to upgrade one owner over another, who would choose, and would it be legal to do so on a regular basis?
Cash room inventory comes from several sources:
1) rooms retained by Disney
2) points reacquired by Disney through ROFR
3) rooms turned over to cash inventory to offset Member trades and
4) breakage rooms not reserved by members at 60 days.
The first 2 types of cash rooms are not owned by members, Disney may do with them as they please, just as any other owner may do with their ownership. The trade offset rooms also are unavailable to DVC members, as these rooms have to be rented for cash to offset the cost of the trade, the alternative would be to raise dues even higher, or eliminate trading to non-DVC venues. The breakage rooms, the smallest pool of rooms available or cash, can be reclaimed by Member Service for point reservation, but again, their would be an expense involved even for the bookkeeping to do so, which would raise our dues. And again, would lead to the question of which owners to upgrade.
