This only happens once a year. Major music festivals like Tomorrowland would need a lot of preparation time and budget because they have to make sure that they will get the best of the best so that people will visit. Some visit music festivals because this is their time to see their favorite bands that they will probably find it hard to see elsewhere.
There are different places where music festivals may be held. There are even some who base the music festivals that they attend in the place where the music festival will take place. This is only practical when you do not have a lot of money to spare.
Tomorrowland festival is an annual event meaning it happens once every year. However, the events spans over 2weekends making a total of 2 exact events. The festivals happen around the end of July, usually around the last 2 weekends of July.
If you want to attend this event, I advise you pre-register before the official sales are launched. Tomorrowland also have events called “UNITE with Tomorrowland”. This event is done in different cities such as Barecelona, Athens, Malta and Porto. The event is done to recreate some moments in the history of Tomorrowland festival. Hope you find this helpful.
