I know I will probably offend some, but its not just the kids; dogs can be just as bad!
We book small family sites/farms, adult only whenever possible (or unless we have the grandkids with us). Unfortunately some of the people with dogs are just as bad as the ones with feral kids! Its not "funny" then rover barks every time someone goes past; its bloody annoying. And then its sets of the chain reaction with all the other dogs.
And dont get me started on people in tents who think they are in their solid wall home. No, the walls arent made of brick; they are made of tissue paper. Yes we can hear your TV/music.
Any of this is okay in small doses and when people are aware and considerate; just having a nice time. Unfrotunately thats not the world we live in anymore. No-one gives a hoot about their neighbours when camping. Me me me.
