I have had wonderful luck at the 7 month window. You just have to be a little flexible.
For example, since purchasing we have stayed at BWV, SSR, OKW, VWL and AKV. We're staying at BCV this summer. We made the decision to try all of the DVC resorts, and I'm so glad we did that. When I called to make reservations, I tried to get BWV standard view, but it wasn't available at 5 months. So, I booked a preferred view. I called to book at the 6 month window for AKV. It wasn't available, so I asked if VWL was. It was, and we booked there. For spring break, I called at the 6 month window, and AKV was available, so we got a "value" room there. It was 45 less points than the standard 1-BR for the same dates. So, I saved some points!!!
I think if you call at the 7 month mark, you have a much better chance. However, there are times and certain accommodations that unless you own at certain resorts, it will be very difficult to book there (e.g., VWL at Christmas, BCV/BWV at Food & Wine, THVs, Grand Villas at OKW, etc.). We don't know what BLT is going to be like, since it hasn't opened yet, but I would say that MK views and standard views will fill up fast. AKV concierge is hard to book, unless you own there. Otherwise, it is the 3rd largest resort, and should be easier to get into at the 7 month mark.
I dearly love the "condo" style resorts, so what I like about them is what others don't. I love that they don't feel like a hotel, that you can park your car right in front of your building, and that you feel like you're away from everything. Depending on where you're assigned, you can have a decent walk to the main pool and amenities. My kids are 13 and 6, so that's really not an issue for me. If I had two or three little kids, that may change my opinion. My DS and DD are 6.5 years apart, so I never had two I was carrying at the same time.
If I had it to do over again, I'd still buy at SSR. I really enjoy staying there, and the fact that it's a great deal is just icing on the cake. But, what you may find out is that you and your family (just like restaurants) may not agree on where you like/want to stay!

I have a definite preference for condo, and DH is enjoying the hotel style resorts more.

See...I should have just left well enough alone, and left him in SSR/OKW world! He would have never known the difference!
