Just had a lovely couple of days at alderstead heath site over New year. The wardens were amazing and threw a nye drinks and nibbles for us all which was great fun, helped us with all the pipes we needed for our first experience on a serviced pitch (my eleven year old will never let me do non serviced again) and somehow managed to keep the washblock incredibly clean and tidy. Showers were amazing. Alderstead is literally a couple of miles off the m23 but surprisingly rural - I went for a long run and only saw cyclists, not a single car in forty minutes. You can just hear road noise if you listen for it, but it wasn't a problem for us.
