The points for weekends are expensive, going mostly weekends is hard to justify.
We bought DVC back in '92, we became Floridians in late '97. For a while our vacations didn't change, one twelve night OKW Grand Villa stay per year. The last few years we have wasted a few points on concierge weekends and the like. I have found Sat-Tues or Wed long weekends to be a fair mix, one weekend day to two or three weekdays(Dean, pretend I didn't say that).
We are staying in the GV this November, arriving the 9th and departing the 12th. We have family all over the country, two different siblings and my father are also DVC members. It makes for easy, comfortable get togethers.
