Definitely fun for a 5 year old boy, I would think. Does he like music and dancing? The characters there are Mickey, Minnie, Goofy, Chip & Dale, so not overly girly. Plus they have a man who does some amazing rope tricks at the beginning.

And, long overdue for the adults only question, but I would say it would be great even if you didn't have kids. As long as you enjoy the atmosphere, music and dancing. It was really a great night both times we went. We enjoyed it as much as the girls did.
