AKL is great for kids. There are scheduled activities throughout the day for the kids to earn beads for a bead necklace. These were the activities and the approximate times when we were there: Flamingo Feedings @ 9:00, Animal Tracking @ 11:00, Junior Researcher @ 2:00, Music of the Savanna @ 5:00, and Animal Games @ 6:30. When all the activites are completed the children receive the totem bead. My kids loved it. We actually spent an extra day at AKL just to do the activities and enjoy the pool. (BTW, we still didn't do everything, but they did earn the totem bead!)
There is also Cookie Decorating at the Boma (1:00ish), Medallion Rubbings (there are large medallions in the floor of the lobby; the kids place paper over the medallions and rub the images using a pencil or something); Animal Viewing with Night Vision, Storytelling by the firepit, Pool Games, Arts and Crafts with the Lifeguards, and a Hidden Mickey search (my kids really enjoyed this, and it's a great way to tour the hotel. We thought it was easier after we familiarized ourselves with the hotel first.)
Of course, there are plenty of places to view animals - not only at the savanna outlooks, but also thru the windows down the corridors. There's also a great gift shop at AKL. We couldn't walk by without the kids wanting to make a stop. The CM's are great about letting the kids "play" the instruments. They loved it.
And one last thing, there is a small playground next to the pool. My kids, of course, loved that too.
Hope this helps! You'll have a great visit I'm sure.
