No, there is not. People with disabilities purchase the same ticket as anyone else. If you need to be assisted during the festival, please send a mail to firstname.lastname@example.org when you have purchased your own ticket, attaching your assistance document, proving you are entitled to a carer. You will receive a free ticket for your carer. Your carer must pay for a campingticket if needed.
If you buy your ticket at the gate, show your carer document so your carer can get their free ticket.
