Take the place! My DS is so happy there. True, decisions don't always go your way but your DD will receive an excellent education and a broad, balanced training in forms of dance that will make them employable young people.
My DS recently didn't have a successful audition for a production because he wasn't the right size. Yes, he was upset at the time but when he came home at Easter he told me he was enjoying getting some 1:1 time with his dance teachers as he was now the only boy left in the class! Knocks come but they bounce back and opportunities such as the one you have been given come along rarely - embrace it and enjoy - we'll see you there?
