This movie could be a disney movie, i'm not sure. Its about a family- a girl and her mum who remarries a guy with two sons. The family visits the mothers mum at her camp (which families come to spend their summer in) and they find out someone across the lake plans to demolish the camp area. The daughter is studying but she meets a guy who is a good dancer. At the end there is a talent quest where the daughter and the guy do a dance together and the guy receives a scholarship.
