Yeah this is correct.
I think if you looked at it at a glance then you can see why people thought that. It's clear though that that setup obviously would not be anywhere near possible at Glasto. It's hard to see where Glasto could fit in tbh. I think Eras will stretch into 2025 then a couple years off you're talking 2028 but also it would have to fit in to a wider tour. And there is 0 need for her to do festivals now unlike in 2019/20.
I've never properly explored the tipi field other than going to Lost Horizons. What is there to see? From memory everything "looks" to be closed all the time but can you just go into all the tipis? Or is it accommodation?
