Children up to and including 6 years of age enter free and do not need a ticket. Children from 7 to 14 years inclusive are entitled to a reduced ticket, sold only at the festival box office on the day of the Event, on presentation of a document showing the child's date of birth. From 14 years upwards the full ticket price applies.
These exceptions do not apply to the VIP area: a full-price VIP ticket is required for every person of any age, including a child accompanying a VIP ticket holder.
Please also read the section on minors below — a ticket is not in itself sufficient for a child to be admitted.
