My daughter has tried Simba's Clubhouse at AKL twice and LOVED it!!! She had a great time - she got to pick her own dinner (chicken nuggets, ff, choc milk) and she mostly colored with markers! There were games to play, Disney movies to watch, toys to play with - and the ladies that watch the children are so nice. Allison was only there for an hour both times, while we ate at Bomas, but she really had a great time!
She's also tried the Cub's Den at WL, and had a great time there too! Again, she mostly colored with markers, but she was playing with some other girls when we came to pick her up. (DH & I had dinner at Artist Point and she wanted to tried the Cubs Den)
Both of these were really nice, and again, the ladies watching the children were great!
