Debated wading in here because as much as I'm known as a Disney hater, I'm known even more as a DVC hater (and that's with family and good friends being 'owners').
I have been to four presentations over the years and a few other special events, like touring BW and BLT before they opened (got a buffet of some sort for BW, a dessert type thing with characters for BLT!)
Now, I have issues with what they do to the quality of a deluxe resort when added (sorry, folks bringing in bags of Walmart groceries doesn't say 'class' to me) but I'll place that aside.
I'd rather focus on the value aspect because I certainly think it is a value for some folks (vastly fewer than likely think so, though).
It all comes down to what I've gone through every time I've had a DVC sales pitch. Do I vacation a lot? Check. Do I go to WDW frequently? Check. Do I enjoy staying on property? Check. Would I like to lock in a rate for 43 years? Sorta check? Would I like to stay in deluxe resorts? Check.
All sounds good, right?
Except Disney bases its value on what they charge for rack rate for the same DVC accomodations during said periods of the year. I'd never pay rack rate to stay at WDW ever, anyway. And I'd certainly not pay say $700 a night for a villa there (don't care that I can have friends and family with me, I don't even like them!) DVC stops becoming a value as soon as you realize you are being 'upsold' into a product you wouldn't normally stay at. Sure, if that villa at $700 a night would be your normal accomodation, then maybe Disney has you. But what if you're perfectly happy staying at a value motel? Oh ... well, Disney's line is prices increase every year, which they do ... but discounts are constant. I can book a room at the All Stars next week for $66 a night (I paid $79 to stay there a dozen summers ago, so how is that a price increase?) ... DVC's sales pitch pretends that there are no such things as discounts and that you have to stay in a 'luxury DVC villa' versus a regular resort room. It certainly doesn't take into account that you can also stay off-property for far less and at other timeshares for far less (some that offer far more).
I think the Pixie Dust factor plays a big factor in some folks thinking. I have a relative who was touting 'owning' a place at WDW as soon as she bought into OKW (she later added points at Vero and BC and dropped her husband for another woman, but that's a whole different story!) She didn't like when I pointed out that she in essence owned nothing at all. She had simply bought into a pre-paid vacation plan and one that makes the points far less valuable the further you travel from your home resort (leave O-Town and they really drop!)
I think it's emotional for many. There's no way it would ever come close to being a value for me (except maybe picking up one of those $35 per point resales for a short time), but I also travel to places beyond Orlando. And I'm a pretty savvy traveler because while I like being a one percenter, I much prefer that I don't spend money at all.
There's no doubt that DVC is doing better than others in the business, but it's also safe to say that the market isn't what it once was (see those 70% discounts at Aulani now for CMs) and will likely continue to be diluted. If there isn't an endless number of rubes waiting to experience WDW, there certainly isn't an endless number of rubes who wish to purchase MAGICal timeshare.
(flame suit on!)
