For me it was the opposite, I stupidly turned down a chance to get Glastonbury tickets for years due to previously having a bad experience at a couple of other festivals including Creamfields due to various restrictions such as entering arenas with various searches, not allowed to bring your own drinks, huge queues at bars, limited amounts of portaloos, no music after dark, groups of troublemakers round campsites etc.
Anyway luckily I decided to give Glastonbury a go in 2015 and was amazed that it was nothing like any other festival I’ve been to with complete freedom to do whatever you want for 5 days with a fantastic friendly atmosphere everywhere. I’ve been every Glastonbury since despite having very little interest in attending any other festival again.
