Music festivals are often as much of an endurance test as they are a place to enjoy yourself, but what has to be endured can vary greatly from person to person.
If we are being perfectly honest, some of the inconveniences that people complain about are kind of self-inflicted. You do not need to be going anywhere near a 100,000+ person capacity event if you hate crowds and noise, for example. Nonetheless, millions every year are lured into the festival circuit by the promise of a party, seeing their favorite artists, and maybe getting themselves some beautifully curated content for their social media platform(s) of choice.
