We are 4 adults who will be spending about 4-5 days outside of London June 21-25th.. We are looking for a relaxing drive through the country side. We just priced basic cost of car at $150 however we are concerned about cost of fuel. Any idea what we would be spending on just the transportation. Thinking of driving to Cotswold or Dover areas. On a previous post I was given suggestions for the lovelier places to drive to however I cannot locate those messages. Thank you for any help you can provide.
