How far out can you book Epcot wind down?

Just wondering if it is 180 or 90 or less?

I think it's only open through November at this point. Maybe December.

Right. But at present?

I think that's it. I don't think it was meant to be a permanent thing.

Currently they are open through the beginning of November and unless they extend it there won't be anymore.

It has been a standard 180 day ADR, but as others have said it is currently only scheduled to run until the end of F&W (Nov 9yh, if I remember correctly). Due to popularity, they have already extended it once; if it continues to sell out, they may decide to extend it again...
