The festival sold out within a few days each in 2014–2016. However, the last tickets for the 2017 festival were sold after 309 days, a mere 2 months before the start of the festival, even though only 10,000 tickets remained after the first day of sales. This was a matter of speculation at first, and reasons such as the changed security situation or the price development were taken into account. Regardless of that, the festival sold out for the 13th time in a row in 2018.
