I think it closed recently.
It is still showing as having hours on the website BUT it says "children 12 and under must be accompanied by an adult" so it looks like you wouldn't be able to leave a child and pick them up later. It's worth calling to find out. https://disneyworld.disney.go.com/recreation/animal-kingdom-lodge/simba-cubhouse/ on the left, it shows hours well into October and there's a phone number for reservations.Oh ok. That was one of the centers to close. I know some stayed open.Bummer. Thanks!
