I wonder, if the problem is locals doing short weekend trips, which disrupt the 5 days standard, might it make sense to make a 'full week rate' which is lower than the (5 x Sun-Thu) + (2 x Fri-Sat) straight calculated weekly rate.
e.g.
Take a 2BR in dream season at OKW. Sun-Thurs. it's 27 point/night, Fri & Sat, it's 64 points/night. Weekly, that comes to 263 points.
If Fri & Sat were also 27 point/night, the total would be 189 points/week, but we'd have weekenders, which are the problem here.
So, split the difference, (189+263)/2 = 226 points/week, or 45 1/2 points per night on the weekends, ONLY if booked as an entire week.
The effect might be good for
DVC for the following reasons.
Occupancy, at these more 'reasonable' rates might encourage more people to take 7 day stays. Overall, this would encourage larger single stay point usage, and larger initial point purchases.
The rooms themselves would be producing revenue, vs. staying vacant, like Richyams suggested.
The point difference between the straight calculated rate, and this weekly discounted rate, would 'eliminate' the need for DVC to fulfill these points which are accounted for in the total point/year count for each resort. DVC could then 'sell' these points as inventory for cash.
Now, I am not sure if any of this is legal, but it is just something I've been curious about. I, for one, would love to do longer stays without having to worry about the hassle of booking the weekends for cash.
