Disney’s sales pitch usually says you will save money over similar accommodations paid in cash. So, considering the ridiculous price Disney charges for a DVC room for a cash customer, its pretty hard not to save money. There is no guarantee to save money over accommodations of another variety, be they value, off site, or other time shares.
That being said, if they do get rid of the AP discount, they’ll be losing some of my money at least. I was planning on adding on points in the next couple of years. Because of the AP discount, we’ve started travelling twice per calendar year or about 11 ½ months apart, but doing so has made us stretch with the points we have available. I had planned on adding points so I could easily afford a 1BR for 1 week twice per calendar year. But if I need to go back to park hoppers, I will likely also return to vacationing 16-18 months apart so that I can refresh my point totals every few years.
Seems like it wouldn’t be a great idea for Disney if I am any measure of the average owner who recently purchased points. Unless thy are banking on owners who have already over purchased needing to use their points regardless, I would think this would cost them more than it would save.
