A well placed site to use as an alternative to the expensive hotels in London.  Easy to get to from the Western side of Londons motorway networks. That's the good part.  However while we have stayed here many times previously, the noise of the adjacent airfield really was intrusive in particular when aircraft and Helicopters were idling / doing engine checks before take off. Have they moved where this is done on the airfield? Lots of jet fuel fumes waft across the caravan site at this time. Not just once or twice but continuously throughout the day. Last issue (and what prompted the review in all honesty)that was apparent during the stay was the poorly thought out 'one way' entry into the site. The site should use the central spine of the site as a two way road, to feed traffic  into the site. We were blocked twice for quite some time between the wardens office and the end of the first section of the 'one way' stopping us being able to access the majority of the site by inept drivers of towing vehicles trying to maneuver. One might accept an occasional wait, but NOT when there are alternative site road layouts that would suit better. Primary school children would come up with a better solution.
