You would think they would rebalance the seasons like that to make everything more equitable... Like make fall more expensive and winter cheaper. But they don't. I believe this is deliberate, and it's not a goal to balance the seasons. Balanced bookings would benefit the consumer... but unbalanced bookings increase competition. Having pockets of unusually cheap times means people will compete for those times. Like Epcot in the fall, or Poly studios ever. It creates the effect of higher demand. It also makes sense to have other rooms be expensive, like the Jan-Mar. These are snatched up by owners from other resorts at 7 mo and creates a 2nd wave of urgency.
A rebalancing to add a preferred category seems more likely. Any time you add a category or division that will cause people to compete for a smaller subset of rooms, that is a division Disney might make. So if Tokelau is hotly requested, then look for Disney to convert this to a preferred category so as to make it something people compete for and not just request.
Lowering the Bungalows is not likely. This is the primo property in all
DVC. It sets the price ceiling, so lowering these would lower the ceiling and that's not a strategy that anyone in marketing will get an award for suggesting. It's good to have something at all price points, even the really high. To rebalance, they would have to be going unbooked -- and they're not. Right now they are selling out, albeit 1-2 weeks out... But then Oct-Dec they are already booked up most weeks. Since these 20 rooms have the best views at the best resort in all Disney, I don't see them lowering the points here significantly. Certainly not 15 points -- that would put them close to a Cabin in cost, and while they are a similar build to the Cabins, they are not a similar location. MK views, Monorail, Poly features and proximity to the TTC set these apart as commanding a much higher price per night than the Cabins.
