My son and I stayed at AKL in February. We were upgraded to a Savannah view, which is certainly better than no view. But it's not worth $50 a day extra. In fact, unless you get up fairly early, you aren't likely to see any animals at all.
AKL has some wonderful public spaces that are really better for viewing than one's balcony. A room view might make the stay more enjoyable, but there is plenty to see without it.
Unless you are just absolutely dead set on having a view, book the standard room and hope for an upgrade, especially if you are going off season. If you don't get the upgrade, take all the money you save and buy dinner at the California Grill and enjoy the view from there.
