Hello,
If the cost is not a problem, I would also say to go with AKL. The building itself is beautiful, and it is a very nice experience to stay there. One thing to note, the price they give you is most likely standard view, so you would not have a savannah view from your room. The savannahs are easily accesible from many spots throughout the resort however. Also, the AKL rooms are among the smallest at a Deluxe Resort, comparable to WL rooms. In fact, I believe they are very similar in size to CBR rooms, which are the largest of moderate rooms. While AKL is set apart from most of the parks, it's no more than an extra five minutes by bus for the most part to any park compared to CBR. And I've never seen a problem with AKL busses being mobbbed as often as I see it occur with CBR busses. You also have a small food court type place in The Mara, while you have Boma for a buffet restaurant, and Jiko for a sit down dinner restaurant. The pool is nothing special compared to other deluxe resorts.
Hope that helps,
Take care,
Bill
