Thought I’d say as I haven’t seen them mentioned in the entire thread. The company that hires the car park stewards is called ctm (event traffic management) I worked with them at Glasto 2019, it’s payed work with a private campsite, proper showers and at least one day of the festival off. I’m not sure if they have any places left this year, but if anyone wanted to volunteer but hasn’t had any luck I thought I’d tell you all about their existence. It does require a £400 deposit though, and the shifts are 13 hours long, it can be brutal, but is still worth it.
