It is the responsibility of the host to enforce the rules. I enjoy a good party and tend to be up late around the campfire with friends. But I still respect quiet time. I have found a difference in our "home" campground on the holidays. Seems that there is a certain crowd or an increase in guest, who don't normally camp that only comes out on the major holidays. Things tend to disappear those weekends as well.
Not standing up for your self and using all tools available encourages this bad behavior. What actions the hosts take is not your problem or concern.
