Re: $140/point.
What if DVC offered BLT with a guaranteed MF cost of at least $1/point/year cheaper than AKV.
They could use "Disney Math' and say you will save at least $50/point lifetime, thus BLT is worth the premium over AKV selling in the $90's (with incentives)
It would depend on how the offer were structured.
One way to do this is with higher point charts. Organically dues would be lower with more points in circulation. Of course, then you're asking owners to not only pay more up front but also require more points per night to stay.
Another option would be to have Disney subsidize the dues reduction. Not sure about the legalities of that--probably is permissable as long as it is disclosed. But from Disney's standpoint, it's largely a shell game. They may get more on the front end but then have to pay more on the back.
And in this second scenario, there would always exist some fear that Disney could maintain this $1 gap by reducing expenses rather than paying out of pocket. It shouldn't be terribly comforting to know that Disney could slash the budgets for housekeeping, transportation, capital improvements, etc. to maintain this $1 discount.
