My first glasto we ended up in a Lionel Ritchie karaoke room in the SE corner, everyone in Lionel masks just singing Lionel tunes. Was incredibly surreal and we spent ages in there. Also miss the Sunday night paint party in the Temple!
I think there's definitely room for improvements for the late night stuff, more of the quirky and weird. Music wise, I'm not a fan of "beats" and think it could be more varied, wether that be the SE corner or elsewhere on site.
