As per previous reviewers, keep yours eyes open for the signs, the sat nav will take you past the turning, well ours certainly tried to.  The lower field is much quieter than the top field.   The toilet block is dated but adequate and I never had to queue for a shower.  The staff were excellent and very helpful, good bus service only a short walk from the site and lots to see in Winchester.  The Science centre by the Holiday Inn is worth a visit, especial for kids, even big ones like us. Had a power cut for several hours on our second afternoon/evening but not the fault of the site.  We would certainly stay there again.
