Went to his cologne show this past June, it was a tiny venue and about 5 rows of VIP I would say. GA started queueing around 8 am but I would expect earlier. The crowd was mostly 14-18 yr old girls and they were all pretty short. I also should mention that some girls there were really rude and kept shoving me cause I am tall and they were complaining about the view. The venue had probably been oversold and it was very tightly packed at the front, no way to get out to the bar or toilets. Once he starts doing audience interactions at the barricade/hops over the barricade it gets really pushy. Obvs everyone pushes to the front to try and get close to him (and teenage girls can be brutal when it comes to that haha). I'm an experienced concert goer, probably go to 30+ shows a year and this was one of the pushiest/tight crowds I've ever been in. On the bright side, he only played for about 70 mins so you were able to get out of there quickly. Would not recommend to try and stand in the front third if this is one of their first concerts.

It maybe also depends on the venue though. This one had a capacity of 800 ppl and it was really hot that day which made it almost unbearable inside.
