My daughter is travelling from Hertfordshire. We asked her school for permission for 3 Fridays off school because we won't get to the rehearsals in Oxford by 1230 otherwise. The school gave permission. It is quite intense. My daughter has done this once previously and they learn a full ballet in 10 rehearsal days. She will also miss 4 Saturdays of ballet lessons at Tring, but we can't do it all, and she will be dancing. They have a class first at each EYB rehearsal which is loosely divided into ability groups, before they learn their dances.
