wdrl has pointed this out.
A factor in your favor is that the resort is not sold out. I forget the exact percentage, but every time they reach approximately 80% sold of the declared inventory, they have been declaring more rooms available for DVC owners.
If they keep this us, there will be approximately 20-25% of rooms available to non-BLT owners at any given time. Also, it's likely there will be at least a couple more declarations before next December.
Declarations just mean that Disney has added made more rooms to DVC members (instead of Disney using them for cash).
