We love our DVC...we started with 150 points in 2001, and added 350 points this year. We are not rich, but we did this without borrowing so now our vacations are paid for until 2042. We'll have enough extra points that we can practically give them away to friends and family and still cover our dues (we've already done that for 2006 with the banked points that came with the contract we bought this year)..
Dues are probably going up less than hotel room prices. Add this to the fact that we know we'll be at Disney at least 3 times every two years, and it made perfect sense for us.
And, yes, it's a condo, but IT'S A CONDO ON DISNEY PROPERTY. That's what makes it special. Walking to Epcot and MGM is worth the up-front investment, in our case. I love having a fridge, a coffeemaker, and a microwave so we don't have to spend $20 each day on breakfast (or get up and travel somewhere to get breakfast during our vacation).
I'm not trying to convince anyone...hey, I said "no" in 1997 when my husband started pushing for it, but I finally saw the light (for us) in 2001. Haven't regretted it yet, as evidenced by our latest investment in more points. We'll be spending 9 days in a std view 1 bedroom at BWV come Oct/Nov for the F&W festival (yes--gasp---we stay on weekends, too). There's just two of us, so studios work, but we like occasionally splurging with the 1 bedrooms. I might feel differently with 2-3 kids, but we're in our 40s, so I don't expect that to be an issue.....
