In past years, four-day tickets (which account for 80 percent capacity of the festival, which typically attracts 400,000 people) would sell out in hours, even minutes, and single-day passes would be purchased even more quickly. In 2016, four-day tickets sold out in less than an hour. Last year, it took about 2 ½ hours for four-day passes to be swallowed up. This year it’s a different story, with four-day passes ($335 plus taxes and fees) still available more than five hours after they went on sale.
