We too have animal obsessed children, and just stayed at AKL for our last trip. We LOVED it!
If you ask at the front desk, they'll give you a kid's activity schedule for the time of your stay. Different activities occur throughout the day for them to participate in. Some of the activities allow the kids to earn a special bead that they string on twine to create a "memory chain" to remind them of their trip. Our girls loved all of the activities (make an animal feeder, animal trekking, animal bingo, African drumming, station to learn how flamingos eat, etc). There are different activities at Kidani Village that you're also allowed to participate in. We had plenty to do at the main lodge, so never went over to Kidani. I'm one to hit the parks and not spend a lot of time at the resort, but this being our first time to stay deluxe and since AKL had so many activities for the kids, we did allocate some time to let our girls enjoy them. So glad we did!!! Makes you fully enjoy the amenities of the resort and adds to your experience and memories.
There are other activities that don't get you a bead, but still great to do (example: storytelling and cookie decorating--they get a giraffe shaped cookie at Boma and get to decorate it with icing and all kinds of goodies, roasting marshmallows over a fire pit by the animal viewing deck off the main lobby).
They have pool parties every afternoon where they played games and then movies were shown late evenings.
There is a drum/music shaker little parade where they get to choose an instrument and sing an African song in the main lobby each evening (around 8:00 when we were there this summer) that is a fun way to close the evening. The kids get a special certificate afterwards.
Be sure to visit with the cast members. Many are from South Africa and can share so much with you. It really adds to the cultural experience. We loved getting to know them. They added so much to our stay.
Night vision goggles can be used to view the animals at the animal viewing area just off from the pool.
There are several animal viewing areas. Each one will give you a different feel/animal group to look at. Enjoy them all.
If possible, I would book a meal at Boma. Wonderful restaurant and it's nice to experience it since it's right there.
There are two activity guides; make sure you get both. One informs you of the bead activities and is small (size of an index card). The other activity guide informs you of other activities (cookie decorating, etc.).
There's also an animal checklist (in your room or given to you with your packet of info) that tells all the animals at the resort to help you and your kids spot the animals and check off the ones you've seen if you like.
Enjoy your stay! We love AKL!!!!
