But in the case of me, we have used all our available points...
But you would have used the points one way or another so no real gain on Disney's part.
...rented points from another owner...
If you hadn't rented them, someone else would have. (And if the renter were a non-member paying full price for park tickets and other expenses, rather than yourself getting a
DVC discount, Disney could have made more money.)
...and the biggest sin of all, have a rack rate room at AoA, exactly what Disney wanted to have happen.
Here Disney stands to gain, but I would question how many DVC members are actually paying for cash trips. Is it enough to offset discounting THOUSANDS of PAPs by another $150 each?
With regard to the travel habits of DVC owners, there are a fixed number of rooms and points. Disney may be getting more of YOUR money because you took more trips due to the PAP offer. But if YOU had not planned so many trips, someone else would have been occupying that room, spending similar dollars.
The real areas where Disney would stand to gain from such an offer are:
1) Add-on point sales from owners who run out.
2) Convinces people who don't normally have length-of-stay park admission to visit the parks more frequently.
3) Some cash bookings from owners.
But again, Disney is also losing money in the process. Every individual who had planned to pay the usual DVC rate for a Premium Annual Pass was able to get it cheaper. The question is whether the financial gains outweigh the losses.
In the case of our family, Disney probably lost money. We had tentative plans to buy single-day admission to Blizzard Beach. Instead we got in free, yet didn't change any other aspect of our spending. We didn't plan any extra trips, didn't buy any more merchandise (even when 20% discount was available), won't be adding any points, etc.
I suspect Disney does come out ahead when this sort of promo is a one-off bonus. But I'm not so sure that the results would be sustainable if the discount were made permanent.
