Safari ride, kali river rapids, triceratop ride, bugs life, festival of the lion king show (which is awesome),daily parade which is also very good, dinoland (carnival games which do cost but you get prizes if you win, and boneyard playground.
Tons of animals to see. I've always found lots of characters at AK too. The last 2 times we went we saw Pooh, Tigger and Eeyore, Rafiki, Terk, and the bears from Brother Bear (Koda and Keani) and best part little or no lines.
My kids also love the water dumpers on the way to the Tusker House.
We have always enjoyed AK, but its a much different experience than MK. There are often entertainers doing dancing and drumming which the kids are sometimes picked out to join in.
Its a more relaxing atmosphere I think.
