On my son's first trip to Disney when he was 5, we asked what his favorite part of WDW was, he would always say the place with the people in yellow shirts....took us a while, but eventually we figured out he meant Simba's Cubhouse! He's been there and Lilo's Playhouse, as well as the one for the DVC presentation, and he loved all three of them. Very safe, very clean, and they do a great job of entertaining the kids.
