I have several comments to offer.
The first is, this is a public discussion board devoted to things Disney. Disney is a wonderful place, and the people here are all huge fans of Walt Disney World. Therefore, if anything, you are likely to be getting responses which are filtered through very rose-colored lenses. Most of us have a difficult time criticizing Disney.
Saving Money
The second comment has to do with saving money. We enjoy our DVC, but in the long run, I suspect it has cost us -- not saved us -- money. That's not entirely bad, because some of the increased cost comes from visiting more often and enjoying higher quality vacations than we did previously. I know it's cost us more...but I can't say the decision (when we made it) was a bad decision.
I think the best way to evaluate the effect of DVC on cost is to think of it as more or less locking in your lodging cost (subject to some inflation on annual dues, of course). I don't look at DVC as a cost-saver, and I certainly don't look at it as an investment. For us, our costs other than lodging have gone significantly up, not down.
Changes in DVC
My third comment relates to DD08's first post to this thread -- the comment about 2010 points costs changes. To us, this week's change may (or may not) be that big a deal. We'll see if and when the Mouse finally figures out what they're doing.
But this week's change is almost irrelevent. The problem we have is there has been a steady stream of changes for about two years now. Many of the basic fundamentals of DVC ownership have changed over the last two years -- always to DVC's financial benefit, and often to our detriment. Some of the changes have been positive, but frankly, most have diminished the value of our DVC ownership. The changes are invariably presented as "improving the ownership experience" or similar drivel, but the obvious truth is they are designed to improve DVC's bottom line.
(I'm a little surprised, frankly, that nobody has started a thread outlining all of the changes over the last couple of years, including explaining the positive and negative impacts on owners. Such a thread would be helpful to new folks considering a DVC purchase.)
The problem with the changes for a prospective buyer is that you don't really know what you're buying. DVC today is very different from the DVC we bought just five years ago -- and I have NO idea what it will be five years from now.
Honestly, if someone asked me today whether I recommend a DVC purchase, I'd tell them no for that reason alone.
Value/Price
I also share Deb's concern with the inflated prices of DVC today...although I'm sure she thought I was nuts when we paid $73! The huge difference is, between 1993 and 2007, DVC consistently increased in value. The last year +, the opposite has been true. The value of a DVC contract has been sliding for a while.
We bought five years ago, and today, our points are selling for less than we paid for them. 2009 is very different from 1993, and prospective purchasers should consider the possibility that they may be buying at the very peak. A time when Disney is increasing their "new" price, but the resale market is tanking, is not an ideal situation if you are buying direct from Disney.
