Didn't book yet. Deciding which view would be best.
If you're planning on booking savanna view, I would do that and then request "close to lobby" (if you're concerned about long walks to your room). Keep in mind that your requests may not be met.
If price is no object, book club level, where you will be guaranteed a view of the dramatic Arusha Savanna. (This is Arusha View, Zebra Trail) and also have access to the gorgeous lounge and yummy snacks.
(Or just book Arusha View, without Club Level.)
OR
book "savanna view" and request "Zebra Trail" (putting you on the pool/restaurant/arcade side of the resort) and "Close to lobby".
However, some of the best animal viewing is from waaay down the trails, far from the lobby. (this photo is of the Arusha Savanna, from near the end of Kudu Trail).
You could book Pool View and save a bunch money

Pool views can be great. (This is an old photo, from pool view on Zebra Trail.)
They can also be lame. (This is from last summer. Ground floor "pool view" near the laundry room and kids club, in the pod off of Zebra Trail)
The view was lame, but the location was excellent
It's hard to pick. But I honestly don't think you can go wrong. AKL is the greatest

Good luck.
