After reading many of the posts, I must say if I read them before my first buy, I probably never would have. There really isn't an ideal person or family that should or should't buy into DVC. There just are people who have, haven't or don't know about it. I was the last category when I first bought. I am single, no children, and went to DW with some friends, we came upon one of the kiosks in the park and I asked some questions. A DVC guide arranged for us to be picked up right then and there, we were taken to presentation at which I bought my first property. Why did I buy? My friends basically suggested that since I typically never take vacations that, if I bought I might be more inclined to get away and relax sometimes. I must say they were right on that account. Since becoming an owner, I have had a vacation about every 9 - 10 mos. I have gone to WDW several times, to Vero Beach, and soon will be going to Hawaii and
DisneyLand. As far as economical, think about it for a moment. On average dues are running about $5.80 a point, to get a studio at OKW is 10 pts a night in adventure or choice seasons, thats $58 night. Where on or off property are you going to get that kind of a rate? And these are considered deluxe accommodations. I know some are going to say, that I am not taking into account my purchase costs. I didn't consider them because, when you eventually sell you are likely to get much of that back, a number of people make a considerable profit. I originally bought, VGC at $110 it is now reselling at $135, a $25 a point profit. I did sell my VGC an bought two others, BCV (the second most expensive property, Vero Beach is most expensive, per available use point) and OKW 2057. Now if I add in my purchase price to the the room rate on average the per use point cost is about $8.35, which would mean that you could stay at OKW for $83.50 a night. Pretty economical if you ask me.
OP asked about Disney helping to make it more available, I have used Disney financing, which made the initial outlay more reasonable, and while financing is never economical for the buyer, it does allow for the getting started. There is no prepayment penalty, so pay more on it as you can.
My point is don't over think it. If you are seriously considering it, you will certainly find value in it.
