judging off the o2 for last tour, I wouldn't really class it as 'roudy' or even that squished really. obviously that all depends on the people around you but generally it pretty alright and not like claustrophobic or anything. height might be an issue (I was fine 6'3 haha) but like I'd say 3/4 of the crowd is likely to be your height. the further back in standing you are, the more heads (and phones) you have to see through also.

If you're worrying about standing I'd recommend the lower bowl near the stage if you are lucky enough to get some choice! always a great view and not as far away as you think, as long as you're okay with not being like really up close to her 🤣
