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.
Topic: Should DVC adjust the seasons to better reflect current demand?
It's all a give and take. If they increase a timeframe like Oct-Dec, then they need to decrease somewhere else. Someone will win and someone will lose. The only sure thing is that everyone won't agree with what they decide.
As to the problems with the late September into the first week of January, I think Disney has caused this problem intentionally, not for DVC but with hopes that the Disney resorts will be heavily booked during the low season from October through mid December. Disney has added more dates for Food and Wine, increased the number of days for Mickey's Not So Scary Halloween Party and added a couple half marathons. So I am not sure reallocating points would eliminate that many folks. It could affect the number of days members could book a room because of a higher point cost. It would definitely affect our trips to WDW.
However, 'el cheapo that I am, when my BIL said he'd take a 6N BLT for Spring I just kinda nudged his vacation into May because the points needed for his stay. He would've let me book Sunday to Friday but not his SO - in fact, I am pretty sure he heard about the fact that I saved points by bringing them home on Tuesday instead of Wednesday. Either way, using over our years allotment hurt less for us plus he'll give us a ride in September to Manhattan for the cruise. Actually, it's a pretty costly ride to the Port.
Our December UY 2017 will be interesting as we're going to aim for 4 trips - Dan's in withdrawal as we mostly cruised this year giving us two vacations with 6 months between each. I'm going to try to trade the AKL points for 2018 March and possibly August so I'll get a real flavor for the 7 month window. I have BC points reserved for 2018 October and I'd really like to hold only the 40 BL points I have left in UY 2017 to use in UY 2018. OMG
By comparison, the heavy demand for early December has been been an issue for years, since before we became DVC members in 2009. Disney has had 8+ years of booking history to justify moving early December from the cheaper Adventure Season to the more expensive Magic Season. If Disney felt a reallocation of the early December dates was necessary, I think it would have done it by now.
I wonder how many people would actually change their booking habits if early December's point costs were to increase. Currently, a Boulder Ridge studio costs 107 points for December 1-14 and 127 points for June 11 - August 15. If those two seasons were flipped, how many people would change their vacations from December to July to save 20 points? I suppose a few members would switch, but not that many. Some members might have to shave a day off their December trips because of the higher point cost, but they might still prefer December to the middle of the summer.
Hopefully there are enough people working around school holidays to keep summer as a high allotment time and early December less points. For example, my Iowa family in laws are going to WDW for the first time in June but they have no choice due to kids vacation schedules.
