The Atlantic Contemporary Ballet Theatre was founded by Phyllis Papa who is a renowned ballerina. I can speak to her summer camp which my sister has been attending for the past three summers.
The camp is not something for children who just want to dabble in ballet and dance, but is geared more towards serious students who want to develop their skills. My sister went to the camp during the first year and has kept going back every since. She says that her skills and technique have improved tremendously and credits the ACBT camp for this.
The camp is mostly girls although some boys do attend. The facility recently added an outdoor swimming pool. Children can come as either day students or overnight. The one complaint about overnight is that the girls are cramped into one or two bedrooms where there isn't too much room to move. They don't spend too much time there, but the quarters are tight.
