I keep hearing how much smaller the rooms are at AKL. I've stayed in a deluxe room there as well as a room at YC. The YC was the same size. Obviously, I haven't seen all the hotels deluxe rooms, but AKL's seemed pretty average sized to me.
As far as luxury goes, I think AKL is just as nice as any of the other deluxes, but it is different. Having travelled to luxury lodges in Africa, I can say that AKL does an excellent job of capturing the feel of a safari hotel. The furniture, art, and even wood moldings were all hand carved in Africa. The lobby is stunning and the restaurants are top notch. It may not be to your taste (it's nothing like the Victorian feel of GF or the nautical feel of YC), but it is a deluxe hotel.
Having said that, I didn't get the same feel at WL. The lobby is gorgeous. The pool and grounds are spectacular. But in my opinion, the rooms are just okay.
