If you're insistent on buying directly through DVC, there will be BLT contracts that come through the pipeline as DVC exercises its right of first refusal (ROFR). You may have to wait a few months, but they do get such contracts. The agents don't actively sell those ROFR'd contracts since they try to push the newer DVC resorts which are not yet completely sold (VGF, e.g.) or about to be released for selling such as Poly.
However, as a few others have noted, if you really want BLT, buying resale will save you thousands of dollars, no question, and there are quite a number of resale BLT (and other resorts) contracts out there. When I first bought DVC many years ago, I was unaware of the resale market since the agents won't tell you about it. When I purchased my first VWL contract several years ago, I went resale and saved over $5K comparing it to direct from DVC. A couple of years ago, my wife and I went looking for another small VWL contract with the same Use Year as our first, and at the time, it was extremely difficult to find one resale, as in we couldn't. We opted to let DVC find us one since the going price at the time versus resale was only a $5-$7 difference per point. Within three weeks we had the smaller contract.
My point is that in most instances, buying resale is a much cheaper route; however, there are circumstances where going through DVC is a viable option. Still, I'd most definitely buy resale unless your heart is set on Poly. As another poster noted, though, there are no 1BRs with the new Poly. So, if you want two studios, you'll have no kitchen or washer/dryer. Food for thought.
