We stayed here for a weekend in low season in order to go to a show in London on Saturday evening. As others have said, you want to give the Tilehouse Lane approach a miss - not only because it's narrow but because the potholes are so bad they will damage your vehicle... We slowed down to a crawl but still managed to destroy two shelves in our caravan fridge and detach the shower head bracket from the shower wall. This problem needs to be made clear at the online booking stage because no-one reads the handbook any more. The welcome we received from the gentleman warden was alarming to say the least; having been held up in traffic (not surprising on a Friday on the M25!) we were running a couple of hours behind but kept the site informed by phone. However when we arrived the warden walked up to the barrier shouting about us f***ing taking the p*** turning up late, and almost refused to let us in the site at all. Once allowed onto the site we felt threatened and uncomfortable whilst pitching our caravan in case we made any noise and disturbed the warden again. From then on our experience improved somewhat; the lady warden was friendly and polite, the site facilities were clean and modern and we had a pleasant 30-minute walk past the airfield to Denham station from where it was 21 minutes by train to Marylebone. We got a cab back from the event in London but asked to be dropped off up the road so we didn't disturb the angry warden again. We made a sharp exit on our final morning and I very much doubt we shall return to Wyatts Covert.
