This is interesting and would make me very happy. They have played on same bill as Max Cooper and Actress recently, who've both previously played the far out late night slots...
I've been in the VIP bit as part of the media/press. I know a lot of people who upgrade for it. Personally, I wouldn't. It's not my vibe and the people I know who do end up spending the entire time in the upgrade bit. The toilets are ok and flush, there's a bar, there's a few extra stalls and freebies. TBH, I don't think I would personally pay for ANY VIP upgrade at a festival now. But that is just a personal preference.
