I've been to both several times and love them both. We were at AKL more recently so we'd go with WL if not for the construction, but I think we'll stick with AKL.
I just booked a studio in Kidani, first time at AKL. Any advice on room preferences? Going next January, it's a savanna view. Really excited about the resort. I can now say I've stayed at every DVC resort on property.
