I thought it felt crowded at times this year. Would 30,000 extra tickets really make it that much easier to get tickets? Maybe a little, but I don't think it would be worth it because the festival would be that bit more unpleasant. I'm not sure they'd need to make the pyramid field bigger though. The whole 30k aren't going all going to go to a headliner, maybe 10k to 15k would. I think the current size of the field could handle that. The issue would be everyone getting out afterwards in a safe and orderly fashion. There's only 2 exits and it's seriously congested as is. Although I've never been involved in a bad crush there I've heard a few scary stories on here involving people with young kids and stuff. I think it got a bit hectic after Ed Sheeran this year?
I think a big walkway that goes through the big backstage area bewtween the other and pyramid would free up the site a lot, instead of going around for miles people could just go through that area on a designated walkway. I've no idea if that's even possible but I think that alone would enable an increase in capacity, but not a 30k increase.
