I've never tried to book a reservation spanning UYs but I would assume that you could call MS and have them do it and over the phone. From my reading you would have 2 separate reservations but I believe that MS can override the 11-month window and book the back end of the reservation for you in the new UY.
You might be right. You can't do it on the website, but maybe Member Services could bridge the Use Year barrier for you. I have never tried, so I don't know.
When spread out over the year, the demand on the DVC rooms has not increased and never will.* There are just as many owners out there as there always has been since each of the resorts sold out. There may be changes to the demand for certain times of year due to changes in Disney celebrations, and there may be changes to what owners want to experience if they bring different sized groups with them or if they've been reading fantastic reviews about a certain category (ex: BLT theme park views).
It should not be any harder to secure that room category you are looking for at your home resort 11 months out than it was when the resort was initially sold out.
I really have to disagree with you here. Demand on DVC rooms HAS increased and will continue to increase. The number of owners and points in any sold out resort do not change, but the DEMAND does. Why? Because, once again, almost any SLACK in the system comes from people NOT using their points. These points expired. Any rooms that sit empty because no one reserves them, no matter which resort and what time of year, represent points which were not used and have now expired. Previously, that was more common than it is now. And even if the room is 'reserved' it STILL could represent expired points. Because Disney can take the Breakage and book ANY AVAILABLE ROOM in ANY AVAILABLE RESORT, for CASH (to Disney) once that room reaches 60 days from expiration and it is not booked. And the points from that room go unused.
Why is it less common for points to expire? (I am not saying that some people's points don't still expire. They do. But it is less common.) People who used to let their points expire, now with the online system need less effort to overcome
inertia and less effort to go to the
work of making a reservation. The online members reservation system makes things quicker, clearer and easier. This by itself helps people use points more efficiently, so less likelihood of loss.
Second, more and more people are Renting Out their points. In many cases, these are points which would have expired in the past. Now, rather than let them expire, people are turning them into cash.
And, third, when HHI, VB and SSR were originally sold, the people that bought them probably bought them because they liked their location, options were limited, and most of them probably planned to mostly use their points at their home resort. But that has now changed. Almost every contract which now appears on the Resale market for VB, HHI and SSR (and maybe to a lesser degree, OKW) is purchased by people who INTEND FROM THE BEGINNING to mostly use those points to stay somewhere else. Look at VB and HHI right now. Rooms are available,
today, in most categories. I know it is winter, but this STILL represents lost points. OR points which are being spent on another resort, thus increasing the demand on the other resort.
My first two points, above, represent increased demand for the entire booking season, 0 to 11 months, whereas the HHI, VB and SSR purchases mostly only affect the 0 to 7 month window. But it is till more stress on the system.
So, you can see why I disagree. I think DEMAND has increased, and the trend is still upwards.
