Hi
Goatfeeder! Welcome to the VWL Groupies thread! Others can jump in here but I'm glad to offer up some thoughts.
Studios at BRV during the first half of December would be very difficult at the 7 month mark. BRV is a very small resort, and that time of year is a high demand
DVC time. Added to that, the whole Wilderness Lodge campus is just perfect for Christmas decorations. So getting a studio reservation at that time can be quite challenging unless you are an owner there booking at the 11 month period. And even for owners, you pretty much have to book right at the 11 month mark.
There has been some talk about the new look for the rooms after the refurbishment, but I can't remember if we've seen what it looks like? I remember that we saw a "test area" for the hall carpeting that looked great. But the rooms themselves I don't remember seeing any information. However, based on recent history, I'd think that the rooms will be pretty similar in decor to what we are seeing now. I suppose they could convert the sleeper/sofa into a Murphy bed pulled down from the wall as they have done in other locations. But I don't see them doing much in changing the layout or amenities of the villas.
Good luck with your decision. SSR and AKV are great resorts too and have the advantage of a significantly longer contract life than VWL which expires in early 2042. So that may come into play for your decision. Feel free to ask us any questions or opinions that you need!
