Sometimes it depends on the room. I was looking at the first days of March and they have the cheap rooms up but none of the other rooms (Superior/Kids suites) available. Usually I can book them 8-9 months in advance. But they may be waiting to see next year's prices for Disney properties before they release everything. I bet you can see them in the next few months. I know that if you're a WDW vet, you like planning way in advance. But DL doesn't require such draconian methods to plan the perfect trip. At least, not yet.
