We just stayed at AKL our first time in Feb. I had bitten the bullet and borrowed points from next year to get savannah view. The first room they put us in was...well...yeah I could see animals, but saw more fencing and edge of pool area. Not what I was expecting after using extra points. I was told to "complain" to the front desk and if I pitched enough of a fuss, they might move us. Well, I didn't pitch a fuss at all, I simply said it wasn't what I was expecting after paying for savannah view. They moved us the next day to a savannah view.
Others may disagree, but I don't think the savannah view is worth the additional cost. When you first get up in the morning, the animals typically aren't out yet....they have feedings and/or checkups in the mornings and I think it's around 9:30 or 10 when they start showing up. Also, there are enough viewing windows up & down the hallway, the lobby and the games area where you're more likely to get a better view. The one exception for me was when an ostrich obviously wanted to get to the other side of the electric fence/barrier area. It kept going back & forth between two points about 50 feet apart, look at the fence to see if there was an opening and then go back. Lather, rinse, repeat ad infinium. I was laughing so hard I almost spilled my tea. I realize they have a brain about the size of a pea and are not known to be the smartest in the animal kingdom, but I just kept thinking....nope, still no gap.
So, with that said, I think you might get savannah view snippets from a standard view, but better to go to the viewing areas/lobby/outside area anyway.
They also have several fun activities for the kids at the resort if you happen to not be at the park every day. We were going to try Boma, but DW ended up getting sick and DD typically doesn't eat a lot and we weren't going to waste a ton of money for a buffet when she wasn't likely to want much of anything. If nothing else, try some zebra domes from Mara at Jambo house (near the pool).
