From my experience, it's been worth it. My daughter has been going since she was two. She loves it. Great for confidence and burning energy. The staff are great and encouraging. We're doing her birthday party there this year too.
We have a trial class booked next week so I can let you know. My little boy is 8 and they've assured me there are other boys there too lol. He's done circus class before with beams and silks but I don't know want he'll make of this.
Following! I want to know this too:)
