I studied DVC for a couple of years before we bought, we visited the resorts, did the sales presentation, thought that we had the knowledge to make an informed purchase. Every DVC owner that we talked to was in love with DVC.
After our purchase and after staying a several resorts we realized that staying at a resort was much different than looking at a resort. Also during the looking phase you are so excited and blinded by pixie dust, that you don't see the little things and you only see the pro and not the con. A long hall doesn't seem so long and for some reason all of the rooms that you looked at didn't have any wear issues, no dings, remembered as brand new.
Today I would make a best guess on which resort to buy or buy SSR just to try out the program. Stay at all of the resorts, experience the inner workings of the DVC, the good and the bad, and be prepared to sell if DVC doesn't work out or buy a different home resort if you have disappointment booking at 7 months.
