I would suggest calling a DVC CM directly rather than try to fish for one on the internet. Well, I would do both.
We had a trip in early May and stayed at our home resort (VWL), and we opted to take a tour of the new Copper Creek model rooms over at SSR. We weren't interested in CC due to such high point costs and high yearly dues. However, we'd been tossing around the idea of adding a small BLT contract since we do enjoy our stays there. We sat down with a DVC rep after the tour (we got freebies is why we did the tours) and told him the new CC didn't appeal to us. We did mention that we'd been tossing around buying a few more points at BLT but knew there wasn't a real active market for direct BLT points through Disney. He said that was true, and that they were popular contracts, so they often didn't have much. "However," he continued, "let me go see what we might have as of this moment."
Miraculously, there were 123 points available, and we could have as many of those as we wanted (minimum 25 points). We didn't wind up buying them as we truly didn't need them (nor did we want to pay the top end direct cost), though we came close. My point is this: the DVC agents will work to find what you want if you push them. This particular DVC rep wasn't our original one (we own both direct and resale, btw), but he was willing to help us find what we wanted. As an epilogue, a week or so after we got home, our actual agent called and said, "So, I hear you guys might be interested in buying BLT?"
We were there a couple of weeks ago, and honestly, we didn't notice anything new. Pool was fine; the CA Grill brunch was very good; and the access to MK is still good. If you haven't been in awhile, then you might not be aware that everyone has to go through some sort of security before entering MK (and the other parks). If you walk from BLT (or CR), you pass through a security checkpoint and metal detector about 50-60 yards after you've crossed the street. If you monorail, you get checked before you get on the escalator or stairs to go up to that level. Oh, one last change that isn't actually about BLT or CR: the new Happily Ever After show isn't as good as Wishes. The fireworks are fine, but much of the show relies on projections onto the Castle, which means you can't see them from TOTWL or CA Grill. Further, the music is now a lot more pop-oriented so not nearly so familiar. We weren't a fan.
