The 5 seasons on Disney Vacation Club points charts were designed to help balance demand over the year. Slower periods were priced cheaper to increase demand while peak seasons were priced higher to lessen demand. However, over the 25+ year history of DVC, the balance has gradually been thrown off. Cheap periods like October and early December are now in high demand while slower periods like May and late-August are seemingly overpriced. Adjustments to the seasons would bring the charts more in tune with owner demand, however members would likely lose some of the more economical stays to which they have grown accustomed.
