I just got back from the AKL today and from what I read, the standard club level room is indeed an Arusha savannah view room and presently costs about $35 - $38 dollars more than a regular (non CL) Arusha savannah view room.
The savannah views are wonderful and I spent more time than I anticipated on my balcony each morning and afternoon watching the animals. But if you want to be able to look out your room window and see your kids in/at the pool, you'll have to forgo a CL room at AKL...
