It’s going to be mobbed, I’d definitely pick a monorail resort if possible so you aren’t relying on solely bus transportation. Poly you could do monorail or boat, or if you really want you could walk since the Grand Floridian bridge will probably be done by then. We are also doing a split stay with Yacht club first, and then we are gonna try to get a DVC reservation in the Copper Creek cabins.... however we have Poly booked as a back up if we can’t get CCV
I booked Poly on cash just in case but plan to switch to VGF at 11mos. Or maybe I'll keep poly cash res (and try at 7 mos) because it was an original resort when WDW opened. The monorail resorts will be sold out for sure.
