Being an heavy traveler, I have never experienced anything like that!
A private social event took place in the hotel.
There were about 50 or so young people partying, screaming and smoking weed in the hotel, even in the corridors. No way we could sleep!
At 3 am, the fire alarm even went on, probably because they were smoking!
On a positive side, I filed a complaint and was reimbursed for 1 night.
