Hi Margaret!
I've heard a number of good things about the Kidani Village. The Savannah side is pretty open to animals, so most of the Savannah Room views are going to offer good views of the animals. I do remember, however, from staying at the Animal Kingdom Lodge, that the staff said you may see more animal activity near the Sunset Savannah, as animals travel to and fro there more at various times of the day. That being said, rooms closer to the Sunset Savannah may offer more opportunity. Or any area close to bodies of water increase the chances of seeing more animals.
In terms of Vacation Packages, you can definitely purchase through either the vacation club or AAA. AAA members can save anywhere from 10%-25% on non-discounted packages.
Just make sure if Disney is offering their own deals during your travel time that you compare the two. You can't apply Disney's Special Offers on your AAA package, so just be aware of that.
Have fun with all your Disney planning!
