As noted, the total points cannot be changed, but how they are applied can be changed by raising the values for some nights and lowering the values for others.
In practice this has happened only once - at OKW back in 1996 - when some nights were raised a few points and others were lowered and some saw no change at all.
Since
DVC began, there has been no change in the seasons except to change the specific dates due to the annual change in date for Thanksgiving and Easter.
Here is the DVC
point chart for OKW from 1991 - 1995. In 1996, the current point chart began and is still valid at least thru 2008 (and the 2009
point charts should be released in the next couple of months). The greatest changes were for Adventure Season, where all room types increased. All other seasons saw little or no change on weekdays, but larger decreases on weekends for all room types.
Points listed are for Studio, 1BR, 2BR, GV (weekday/weekend) respectively from
1991 thru 1995:
