Wave Gymnastics

We tried to do a trial with our 4 year old. There is no real viewing space for the little kids section. There is a small window you can hover over from the sidewalk. The main gym is only viewed by everyone sitting outside through a garage door. Everyone is leaning over each other to see or find their children. All of this we would be ok with but they leave the front door open during class and my 4 year old daughter ran straight outside and around the building and to us in the middle of class. We were very lucky she did not run straight out in to the parking lot and get hit by a car. We were so confused because we did not know if class was over or if she just ran out unsupervised. No one came to find her for 2-3 minutes. I tried to discuss with one of the owners and she just kept speaking over me and did not give me the chance to explain. She made up excuses about leaving the door open for fire code but then said the door is closed in winter. The place has good ratings overall and I really want to give it another chance but it does not sit right with me that a child could just run out into traffic. Additionally, the coaches and front desk person seemed incredibly young and clueless.
