First and last time in 2012
My class was on a 5 day trip and the camp we stayed hat had a big free-time area including a kids-place with slides, a swimmingpool, a cinema, a burger-place, a grocery store and a disco.
Most people in my class wanted to go to the disco. Everyone under 18 could stay till midnight and since you can drink beer at the age of 16 my teacher thought to buy everyone (over 60 students) a beer ... the disco was pretty small so us around 70 people plus maybe 30 other visitor made the room almost explode lol
The 'DJ' was some random guy standing in the bar-area with a laptop playing music and in the back was a large screen that showed random images or the MVs of the songs ... The room was maybe 10x10m and had 3 high tables with high chairs to sit on and the rest of the place was the dancefloor
Thats it
