well yes, i think most of the sites i go to seem to find it...the new forest ones all seem to have people awake but not making a racket...
me & Dh usually sit outside so as not to disturb the children, drinking and playing computer games. An, sadly, yes...thechildren do wake up early. and not quietly.
bit like most caravanning & camping club sites...they don't seem to attract super-rowdy groups, but don't feel the need to crack the whip either...
