Just because it's not sold out doesn't mean there is space available/rooms sitting empty. In a traditional condo/timeshare development those rooms most likely would be sitting empty till they where sold. But that isn't how Disney and Disney Vacation Developments (DVD) do things. DVD gets the rooms from Disney, they declare them into inventory, and can start selling them.
Right now there is something like 75 rooms in inventory (I think people said there where 50 in Oct and another 25 or so in Jan.) So that means there are like 10 floors of rooms which Disney still owns and DVD can't sell.
So if you wanted to do a Cash Reservation. Now is a great time. Because Disney has the rooms in there reservation system.
Now I'm not sure if DVD can book rooms that Disney owns and they somehow "pay" or if DVD can only book an average of 75 room-nights for the next 11 months. I suspect that DVD can "pay" for them, but I'm not sure.
However, there is a HUGE pent up demand from
DVC members for the rooms. People have been wanting a "DVC Monorail resort" since 2002/3 (which is when I started following DVC, I took the 1990's off from Disney.)
So I would guess in the next 5 years or so, the demand for BLT will drop down (especially since the per night cost of the rooms is high compared to other resorts.) Look at how much stress people have about them raising the point costs durning the week, in the low season. I don't see anyone complaining about the corresponding drop over Christmas. (Because over course of a year the number of points at resort can't increase or decrease they can only move the points around.)
Now that is more of an explanation that you wanted. So to answer your question. Stay at DAKV, we love it, it's our home. Book BLT when you want change.
