Has anyone been to one of these before? We are going for the first time this weekend (Midlands North) and have been told by the dance teacher today that we aren't allowed to leave the theatre at all during each section. That would be 4hrs and 10 minutes- Lunch ends at 14.10 and tea starts at 18.00. That's not one class, by the way, it's 5. I know you don't leave within a class! Surely this isn't right? She's only in one group dance and we have somewhere else to be! Anyone shed any light on this?
