I really have to say that AKL is a destination unto itself. Pool view should be wondeful. You will have access to the Savannah view via Arusha Rock. The thing is, there's just too much going on at AKL that makes it stand out as it's own destination. The architecture, the organized children's activities (such as campfire story telling and nature talks) and the overall ambience of the resort. If you have the opportunity to go there, even though ASM is nice, you're in a win-win scenario.
If I had to sum things up, I'd simply say "DO IT!"
