I like your ranking system! It's very scientific and I think it gives you a good idea of the merits of each resort. I may even do one of my own just for jollies. I've stayed at every WDW resort but Copper Creek. And that one may be on our list soon now, but as you know, I really want to stay in a cabin!
I would use different categories, like you said, it's very subjective and different people value different amenities. Location, theme, and rooms, I would keep. Pools don't matter to me. I have a huge one in my backyard and I don't utilize it nearly enough, I use the pools at the resorts less than half the time when I'm there. Amenities is something I would split into Tub (in the room), dining options, and spa services.
You'll have to see how my results differ! One thing about your stats is that your family is almost always in a studio, where as we are almost always in a one bedroom. You've rated the Poly on top, but I suspect that it may be lower on the list for me because they don't have a one bedroom, so the Studio ranks lower because of the tub. The bungalows rate very high, but perhaps I should put a column for affordability as well.
I really liked our stays at SSR, for me proximity to DS and the dining options was great. No it doesn't have the best theme, but it has the secondary style of jacuzzi tubs which are nice and big and I can be fully submersed. And they have an excellent on site spa!
I prefer Kidani over Jambo house because of the two bathrooms in the 1 br, and Sanaa is my favorite restaurant at AKL. I'm not a fan of the Mara, Fran doesn't like Jiko, and neither of us eat enough to make Boma worth it. So it's great that there are different choices for different folks!
And IMHO OKW has the BEST tubs ever! I can't wait to stay there again for that alone!
Great trip you had and I'm sorry we'll be missing each other this summer.
