Along with my mother-in-law and sister-in-law, I will be visiting Highclere Castle and Stonehenge this upcoming August. I'd like to take the train to some town outside of London, pick up a car, and get a room/apartment for two nights in the area of Highclere and/or Stonehenge. My question is this: How far do I need to get outside of London to find a decent town in which to get a car AND be outside of city traffic. It would be really convenient to find a train station with a car rental place in it.
Thanks!
