The only thing they don’t want is swimming short, shirt less and flip flop ! In the past they were quiet some people wearing those in all the club except Pacha..
But with trainer , short and t-shirt you will always be fine don’t worry...
When I went to elrow at amnesia (2016 or 2017?) in June everyone was free to go up to the balconies, it was my first time being up there and it was good being able to just nip across and look down at the main room.
It was a nice surprise being able to go up to the balconies.
