I don't know if this helps, but back in 2000 when our DSs were big Buzz Lightyear fans, we went to the "Buzz Lightyear Dance Party" (Stitch was probably just being drawn back then!).
We had no problem getting close to the stage. And we probably only stayed 15-20 minutes; there were a lot of people coming and going. I remember the DJ playing "Who Let The Dogs Out" at least a couple times! And I remember it was really loud!
