We were having a weeks stay with friends. We were arriving hopefully at same time as to pitch together. Unfortunately they got delayed by a accident on motorway. So they were 15 minutes behind us. We wanted to save pitch next to us for that short period. But  the answer was no way. So in that 15 minutes empty pitch next to us went. Friends ended  up on other side of site. This spoilt our stay. We spoke to other people who had same problem. I can understand when people want to save pitches for hours. But 15 minutes  !!!!!!. The site pitches were poorly maintained. Water points very dirty. Location excellent.
