As you know, the points are laid out in a chart that covers the year and the type of accomodations. The total number of points at any resort will never go up up. A particular unit, day, time of year can go up but if it does, something else on the chart has to go down.
Dues have gone up and down. They have stayed fairly consistent over the 10 year of DVC. At OKW, 5% increases were seen in the early years. Then there was a stretch of about 7 years where they fluctuated up and down a few cents. Last year there was a significant bump driven primarily by insurance costs for the resorts and health insurance costs for the CMs. Hopefully, this will not become normal. DVC does an excellent job of trying to contain costs. By FL law, the dues (except property tax) can't go up more than 15% in a year. DVC also consistently puts away money to cover big ticket items like roofing, painting, etc. so there should not be a big "hit" when it comes time to perform these maintenance tasks.
OKW dues have gone from $2.56 in 1993 to $3.49 in 2003. BWV dues have gone from $4.02 in 2000 to $4.10 in 2003.
