We stayed for a week in August 2015 with our 11 year old Grandaughter.  The site is extremely well maintained, all the staff are very friendly, helpful and knowledgeable. It is in a good location for getting to London.  A great idea in the information office is they have take away slips of paper with full and accurate directions to all the popular London attractions.  I would suggest though that non CC members be given a written sheet with some basic CC rules, mainly about late night and early morning noise.  I will not detail it but we were disturbed regularly, that is not a reflection on the Wardens just thoughtless people on holiday.
