We've visit this site several times a year and are aware of the site rules and arrival time. We arrived 20 minutes early and were told we couldn't wait in the usual arrival area. We were told to leave the site and park in the park and ride car park. When we returned at 1pm, there were several vehicles in the waiting area. We were then told our new vehicle was too big for the site, it is 29cm too big. We had updated our details through head office and the app was upto date. The warden was quite abrupt and said he'd let us on this time but this would be our last stay, we pointed out we'd be to this site only a few weeks early with the same vehicle and no one told us the vehicle was too big. The warden said the reason was because a child had been killed on site, when I went online, the accident was caused by a towing vehicle and not a Motorhome. That night we noticed 3 other vehicles on site which exceeded the size limit, one vehicle was bigger than ours. We asked for a late departure as it would be our last time at the site, the answer was no. During our stay, we noticed the wardens pointing towards our vehicle as they drove past, and as we packed away on our departure day, a warden went behind our van to reposition the wooden stake, but we hadn't hit it. It felt as if we were being intimated. If we had known the arrival area was not to be used, then we could have avoided the first problem. If we were told our vehicle exceeded the site limit, we could have avoided the second problem. Instead our holiday was ruined. We will no longer be able to visit that site.
