I have a different theory. I think that many buyers were duped into buying VB by their lying sales people. These people realized that home resort DOES matter and are trying to dump their worthless points. Worthless because they can't be used to secure reservations when wanted. People found out that the seven month window does matter.
Think about the lies we have hear here again and again.
We have had many people report of sales folk saying:
"Since most reservations are made less than six months out, the seven month window doesn't matter"
"Sure, VB dues are highest now, but dues vary and they were once lowest and could be again"
"Buy at VB, the money you will save with MB will be great and you can use the VB points whenever and wherever you want"
I think many people realized that the seven month window does matter and they were lied to.
More realized that VB dues were always highest, Disney had a subsidy that made them lower, this subsidy ended when they realized their failure at VB and dramatically cut the scale of the project.
Even more realized that you can't use VB points whenever and whereever you want.
For the previous poster, VB dues would eat up any savings pretty quickly and the headaches associated with being forced to use the seven month window would lead to frustrations pretty quickly. Also, there is a remote chance that VB will never sell out and that Disney will want to cut off the bloody stump. You could buy VB and one day not have any affiliation with
DVC.....No WDW resort stays at all.
