Organizers of the Defqon.1 hardstyle festival in Biddinghuizen, Netherlands, have drastically reduced attendance this weekend, cancelling access for nearly 30,000 ticketholders due to extreme heat. Only visitors with weekend passes will be admitted on Friday and Saturday, with day ticket holders excluded. The decision aims to improve safety by allowing for better crowd distribution and increased access to shaded areas. The festival, typically attracting 72,500 attendees daily, is proceeding with reduced capacity from Friday to Sunday. Attendees expressed frustration with the late notice of the cancellations, citing significant financial losses due to non-refundable tickets and accommodation. Organizers acknowledge the difficult decision and prioritize visitor well-being amidst the heatwave.
