Oh how I wish the Poly had DVC...that would make this choice so much easier...lol. Both DH and I loved the Poly when we went there for breakfast at 'Ohana's and walked the resort. If he stays solid on the SSR choice then I will definitely be prepared to wait and walk and leave enough time to get to ADRs.
i believe that there were rumors of a possible poly dvc being built after the gf dvc but i am sure you don't want to wait that long (if the rumor is even true)
