Please help out some kind of older folks

We used to attend Sziget regularly around 2001-2006. Since then we have only attended smaller festivals but I still have very positive memories of Sziget and the general atmosphere. But we have specific concerns about camping now, especially the access to toilets and showers. I know there was a similar post recently, but I'd love more information if that's possible. Our camping equipment is in good shape so that's no concern and I think I'll book camping of nations to be extra sure. But how is camping of nations? How many toilets and showers do they actually have? How far away are they? I know it's not silent camping, but is it not too wild or do people play their own music and party all night long at their tent? Do I need to worry about drunk people pissing in our tent at night for the fun of it? Because honestly, I'm over that. I'd probably book the moving in ticket as well, so I hope to get a fairly comfy spot. As I said , we do attend other festivals, but small ones with a chill vibe on the campground. I don't mind when people go crazy in front of the stages, I hope everyone has a great time, but I also want to sleep.
