Most of the employees are high school students and I have never seen an actual adult in the mix. Most of the time these kids are just talking to each other and not paying attention to the kids playing, of course the parents are there too during the week but most parents are sitting in the benches. I have seen a couple of kids pushing others and I had to be the one to call their attention because my son was close to them. They have "parents night out" where they take care of your children but I wouldn't trust high school kids to take care of my toddler with a group that will have all ages and where the high school students won't pay attention to what the children are doing. There is plenty of high school students the few times I have visited (4-6) but I am still watching my two toddlers.
