problem is it's become way more popular, especially closer to the weekends. Yesterday no one that joined the queue after 8am were allowed to even join the queue. Joining for evening queueing is not a thing as a result also. People that arrived at 6am yesterday were queue number 10k. Joining at 11am on Wednesday when it was quieter you maybe had a chance getting in, but at 8pmI remember me and my mates got there first around 11am and we didn't get in until 5pm. Learnt from that.
Evening queueing is not a thing because of the popularity, but even the show court ticketing is a mess. You sign up for resale in a digital queue to get one of the main courts, but this relies on people who leave the main courts to scan their tickets when they exit - which many don't do. This is why you are seeing so many empty seats on the main court in the evening games on tv (e.g. Raducanu last night) - loads of people on the hill who would want the ticket, but no way to get it, and no way for someone leaving to just give a ticket to someone as they leave as it is all digital.The other thing is to go really late ie join at around 4pm and then by then peeps have had enough after a long day and start leaving. One time got lucky and some old gentleman gave us his 2 tickets for court 1 as he was leaving. Got to see James Blake IIRC.
Never tried camping out the night before though as they release 500 tickets for the show courts.
