I went again recently (less than a year ago) for the first time since the 90s and the animatronics stage was still fully functional. Apparently very few locations are left with working stages, and I was impressed that my local stage had continued operating. They also serve alcohol now or something.
It felt a bit more open, one giant room, but I might just be remembering more walls because I'm taller now than I was when I was 10. Definitely no ball pit though.
