And that is a big problem. While they can contractually reallocate points for demand, major changes, such as increasing points for early December, are likely to create no problems than they solve. There will be a lot of complaining, and ate possibly some lawsuits if the changes are drastic enough. Meanwhile, you drop the points to go in April, that doesn't mean April people a happy. Not every DVC member had unlimited vacation time to use all their points and you don't want to pay dues on points you aren't using. And then Disney marketing adds rum to dole whips in April, puts in a bicycle race and a hot air balloon festival, or hosts an international Lego tournament, and then the points are out of whack again because you've increased demand.
