the hotel prices are increasing. So the point value will increase.
That's not really a valid justification.
Let's say a guest wants to book a CR Garden View room with points. During Regular Season that room currently costs 32 points. Using those 32 points, Disney can pull 4 OKW Studio nights (Adv or Choice Season) to try and rent thru CRO to make back the money.
The CR room, which costs $259 per night today, WILL increase over time. But so will the price they charge for the OKW rooms (currently $279 per night.) Disney shouldn't have to raise the points to increase the revenue earned on these trades.
The biggest justification for point increases is reduced success in renting the rooms thru CRO. Obviously they aren't going to rent 100% of the villas turned over to CRO. Let's say that at one time they averaged 60% success in renting
DVC units thru CRO. If that number has since fallen to 50% or 40% or 30% success, DVC will need more and more points for external trades in order to just keep trading at break-even financially.
I don't know that I would agree that "not many" people know about point renting. That may have been true 5-6 years ago. Now just about ever Disney-themed website or guidebook has information on point renting.
I may well be wrong about the cash demand for DVC villas, but my comments are based upon the following facts:
1. Point costs for non-DVC destinations keep going up (see explanation above.)
2. Frequent posts from people asking "why can't I book ___ with my points, but cash guests can get it?"
3. Point renting has never been as mainstream as it is now. Just look at the traffic on the R&T board. I'm not saying that the cash market is non-existent, but I don't see it as being in a growth mode. At least that's my take on dual-use facilities where you can book the same facility with either cash or by renting DVC points.
4. All of the recent Developer's Points incentives. This summer they were giving double Developer's Points for AKV and SSR purchases; someone who bought jus 160 at AKV would get 320 Developer's Points. That's enough to book a Savanna View Studio for SIXTEEN consecutive nights. At a cash rate of about $280, DVC gave away almost $4500 worth of points. That's more than just an incentive--to me it's an acknowledgment that they can't find a more profitable use for the points.
