I think adjusting December 1-23 points charts would go a long ways to addressing frustration with how hard it is to book during that time. It is far and away the time of year where you save the most money over rack rates and it’s a lovely time to visit WDW. No wonder members using their membership for personal reasons or for spec rentals target that period. Meanwhile, summer will cost you more points for rooms that Disney sells with up to 40% discounts off of rack rates. Or, compare it with Oct/Nov - is early December really less in demand than Oct 1 - Nov 23?
I think pre-COVID, people probably didn’t take off time from work or school between Thanksgiving and Christmas. So, that period truly was a lower demand time. In the age of remote work and school, I think people have gotten comfortable taking time off whenever they want and doing whatever work or school they need to do during that time from their laptop. And, if they can score a great deal at WDW during that time, they’ll jump at it.
