How on earth, and who can police day visitors in order to charge them ?
Everyone camps too far away from the gate. However many advance tickets are sold, there are always the last minute people who turn up.
As for cutting the number of bogs.... it was me who suggested we need 4 in the summer... three is the absolute minimum. We should not have to be cleaning them all the time if people were more considerate. V.T. has a good point about paper usage. On past camps I've noticed that the washing (hands) water has often run out because people wash and brush up, and blokes shave in them. What's wrong with a washing up bowl in front of your uinit chaps? It's all cold anyway, but you could boil a kettle for washing.
Always bring spare loo rolls too, then there'd be enough to go round.
