Be ready to come up with activities for gym and art, and to set up. There is a game room where the kids can play games. There is a pool, but lifeguards are not always there, and you do not usually know that in advance, so be prepared to come up with something else to do. There are fun trips that you and the kids get to go on that are paid for, and lunch with them is fun.
I worked with the younger girls, and my co-worker who worked with the middle aged girls often teamed up with me. I cannot imagine working there without her, for she was a great help.
