Super croweded all the time....I have given up trying to go to classes. I can always find other machines though. The kid area is pretty nasty, but no worse than the local mcdonalds. I take my 4 and 7 year old there occasionally but I still refuse to take my 15 month old. I feel like he will put something in his mouth and come home with nasty germs. Plus, It's pretty much a mad house in there. I don't feel like they are high on security. I know my older two would only leave with me but a baby that doesn't talk and loves to hug everyone is a different story!!!
