Let's say(extremely unlikely, but you never know) in 5-7 years, there are 3 addtional
DVC resorts built and available and all 4 including SSR contract till 2054. Would then be a time to introduce a 3rd booking window. Example for a BWV owner like myself
11 months - BWV-Home resort
8 months - BCV, OKW, HHI, VB, VWL
6 months - SSR, Eagle Pines, Villas at Animal Kingdom Lodge, Villas at Disney's
Castaway Cay (Just dreaming

I've never been there and not sure if there's even enough land)
The 8 and 6 month vice-versa would be for the two sets of resorts and expiration dates
Let me know if this sounds fair or reasonable.
Peace,
