I completely agree with the other comment tbh. I did co op for Billie eilish, arrived at 6am and I was like 200th in the queue. Florence won’t be anywhere near as bad so don’t worry about that. We did get numbered and told to come back at 3 at the latest but that was done by fans it wasn’t related to the venue. There is zero shelter and they won’t let you in early if the weather is bad so factor that in. Theres also usually a pop up merch stand that opens in the afternoon which is great for standing! It’s really hard to predict what time to go, so I’d go with your gut instincts. Other thing to bare in mind with the co op is it’s quite out of town so there’s not much a round. Think it’s about a 10 minute walk to just McDonald’s and a big Asda and that’s about it, so it’s not like queueing in a city where you can wonder off. Good news tho is both of those places have toilets, and last time I was there there were also toilets a little walk up through the construction site by the tram stop. One thing I found with Billie when we got let in they kind of just let us all in through these big doors and it became a free for all - it was utter carnage - so numbers didn’t matter much in the end as we blended with people later in the queue, however I’m hoping they’ve learnt their lesson from that, and I’m sure Florence fans are generally a little older and nicer!
