Last Sept, my dd9 stayed one evening (you can stay anytime from 4PM to midnight) at Simba's Cubhouse. We ate dinner at Boma and enjoyed time at Epcot. And also one evening at the Neverland Club. We ate at Kona Cafe and headed to the MK.
For ages 4-12, there are coloring pages, board games, movies, video games, crafts, etc. They are also fed dinner (PB&J, carrots, milk, etc.). We picked her choices upon checkin.
My dd enjoyed the activities, the games, and the friendliness of the CMs much more at Simba's Cubhouse. She is asking to go ago on our next Disney Trip. We asked not to go to the Neverland Club again.
I believe that younger children will enjoy the Neverland Club. And older children may enjoy the Simba's Cubhouse better.
