Has anyone been on the Camping and Caravanning site at Waltham on Thames south of London.? If you have can you let me know if there is a short cut to walk to the Train Station? I will be staying there while my daughter is in Hospital in London for 3 weeks and will be comuting every day.Ido not walk too well so if it is some distance i may nrrd to get a taxi each way which will add to my costs greatly. Any ideas or local knowledge please. Carol Slinn.
