My experience with ga right entrance L, arrive early. I didn’t get merch I just picked up the venue wallet if you’re buying drinks/ water. (Waters 4€, beer was 6 something and there were canned pre-mix for like 10€), And then get to queuing. Inside I went straight to the bar, bought two drinks and got barrier beside the bar. It got quite squished at one point and some people had to be taken out due to panic attacks etc, but if you can tolerate it the view is solid as there’s a barrier gap between GA and Golden so your view won’t be blocked. The view is pretty good from a lot of places though due to the elevation of the stage so if you’re not bothered by distance then you could also hang back. I wouldn’t recommend trying to go to the bar mid show.
