I love SSR. We stayed there before the retheme in a 2-bd with our family of 6 (DH, 2 teen DS, mom, and MIL--OY, never again with mom and MIL

). We had plenty of space and we were right next to the paddock pool. I think if we go again with my mom, we'd definitely do SSR. I love the look of the new retheme, especially with the new Murphy bed in the living room. But we tend to rent a car and only use the bus for our MK day(s).
I'd probably choose OKW over AoA just on size and beds alone. The beds at AoA look so uncomfortable with the pull-down murphy beds onto those tables. At least with OKW there are the boats that you can take to DS. I know people love the Skyliner, but that thing looks like such a hassle in the morning rush to get to Epcot/HS, especially from AoA/Pop (anywhere except CBR).
