Here's a resolution of sorts for you all.
This morning December 14th was still unavailable, but the 15th showed available. Later on today, the 15th was also taken out of service, which means a certain number of rooms are being removed from the inventory for some reason. Perhaps its tenant improvement work below, or something, but 11 months is an extremely long time frame for that.
Anyway, two days of resort view were available, so I took them and waitlisted resort view for Sunday if that came up, intending to replace the Boardwalk view with the resort view. Later in the day, I did some checking and found that Sunday the 13th did indeed come up as someone walked on by, and I quickly canceled the Boardwalk view reservation and modified my resort view reservation, and with the points saved extended the reservation to the 17th. So I'm not getting my Boardwalk view (I'm 0-2 on that, due to renovations both times!) but I'm getting an extra night at the resort. I'll just have to keep the drapes closed so I don't see the dumpster outside my window!
