If you have a child\children who are currently in possession of a child ticket but will be 18 at the time of the festival then they will need to have an adult ticket issued.
The organisers acknowledge that the postponement of the event isn't your fault and are happy to honour the adult ticket at no extra cost.
To request this, please raise a support request and provide your children's proof of age\photo ID. Skiddle will then cancel the child's ticket and reissue a complimentary adult ticket.
