Tomorrowland is a well oiled machine. It sells out faster than any other festival, even with the addition of a 2nd weekend the festival tickets are gone in the blink of an eye. Just as with years past, Tomorrowland 2018 sold out within an hour today.
Prior to today there were other ticket packages available, but the worldwide sale kicked off today. The full phase 1 lineup was announced over 2 weeks, but now your only chance to attend Tomorrowland is to buy 2nd hand. Surely it will be another festival for the ages.
