For those of retirement age,
DVC can evolve from family vacations to a warm weather escape in the winter months. We look forward to using our points to stay at Vero or Hilton Head during the winter when our kids (now 18 and 21) are out of the nest. It is far less expensive than purchasing a second home or condo, worrying about hurricanes and paying taxes, maintenance, etc. DVC takes care of all the maintenance and you are not going to find a reasonably priced condo with the beauty of Hilton Head or Vero or OKW.
For just two of us, a studio will be fine and our 420 points will go a long way. The flexibility of the point system as opposed to a fixed week (as well as the quality of accommodations) was what sold us on DVC. So, if the kids want to join us, we go to a 1 br or 2 br.
Like many previous posters, we bought 230 OKW points in 1996 after going to WDW for the three previous years. The points cost less than the three vacations had cost. We added on twice at Vero, taking advantage of special offers. Though the maintenance costs have risen, we still get far more value than the annual maintenance cost in our vacations. Florida real estate is leaping up in price and that cost will be passed on in higher prices for accommodations in other new and renovated resorts.
So, we see our DVC purchase as both a vacation option now and a retirement benefit in a few years. We're very happy with our purchase, and would still be very happy even if there was no resale value. Our guide, when we purchased initially, told us straight out not to view DVC as an investment, so the resale value is an added plus we didn't expect.
