I signed my daughter up when she was 4 for a 4-day summer special. She got teenage or early 20-something girls as teachers and the 3 girls in charge of the tumbling didn't seem to know how to handle the large group. They constantly talked to each other to reaffirm what they should be doing. During the dance portion, there was an experienced instructor who CLEARLY knew how to handle a group and kept all the kids moving. Even the crying ones. She even held my daughter to calm her down but continued teaching as though this is normal. I was disappointed when the 4 day class started as they separated the kids who were actual students of the gym from the ones who signed up through our local parks office (which was my daughter). All in all, I was pleased that my daughter enjoyed it so much and still remembers it even a year later.
