The standard rooms overlook the entrance of the hotel (the outside). I don't know if you can see the parking lot from the rooms, but they do face the parking lot. You will have to walk through the main lobby to find a viewing spot of the animals. But they're all over the resort, so I wouldn't worry too much. The AKL is all one building and it is in a horseshoe shape. We stayed there in December and had a Savannah view, but I don't remember the "trail" we were on. Each hallway is called a trail. I want to say we were on Kudu trail, but I really don't remember. If having a view of the animals is that important to you, I suggest you make the reservation for a savannah view room. If you don't think you'll mind walking to a viewing spot (and it wouldn't be a long walk) then stick with your standard view.
Hope this helps a little.
