I've been able to get (almost) anything I've wanted at the most crowded times as long as I call right at the 7 month window. For example, we are staying at VWL from 12/22 - 12/30, and when I first called MS to book a 2 BR, I had my choice of resorts except for VWL. I could get all but the next to the last night, so I decided to book at BCV instead so we didn't have to change rooms. Two of our last 3 stays were at BCV, so weighing in late in the game, DH decided he'd rather stay at VWL. I called MS back (about 2 hours later), and a 2 BR was now available for all nights except the first. That was a much better option, so I went ahead and booked a studio (cash with
DVC discount, as a studio was not available) and a 1 BR for the first night and wait-listed a 2 BR. About 3 months after I booked, my wait-list came through. I wasn't holding my breath, though, as Christmas is a super-busy time. It just happened to work out for us.
If you're flexible with your dates and/or room size, you probably have a pretty good shot. We never book studios, so I can only comment on 1 and 2 BR villas. Plan your alternatives in advance, so if your first choice isn't available, you can move right on to your next. You'd be amazed how quickly inventory changes from minute to minute when you're on the phone with them during peak booking windows.
Best of luck!!!
