I don't know if its fair to compare a
DVC resort to another non DVC resort (even if its a Deluxe one..)
I have never stayed at OKW, but usually visit the resort once a year... I enjoy the sense of community of the resort, and how it feels like a private "condo" community nestled in the heart of WDW..
I somewhat familar with the room layout, and the Studios are generous in size compared to a normal room at a WDW resort.. Plus you have a kitchenette with a small fridge and microwave... At OKW, you would also have access to a Washer/Dryer.
While staying at OKW, Olivia's is a great place to eat...
My family stayed in a Savannah Room view room at AKL last December. The room was surreal... (Smaller than the OKW studio, mind you...) But to be able to watch the elk, vultures, and giraffe from the balcony was awesome! We would order room service and eat on the balcony just so that my three year old could watch the giraffes chase the food truck around the Savannah...
The decor was nice... The pool was themed, with a slide... (Construction on the OKW pool slide will be starting shortly.) If you stay at AKL, I would HIGHLY recommend Boma's... All you can eat African Buffet... The food was great!
I really enjoy each resort, and don't think you could go wrong either way... It really all depends on what type of atmosphere you are looking for, and how much you wanted to spend...
