I am due to travel to London from Exeter on the 11 July 2014. I am guessing my roote would be to travel up to Bristol on the M5 then across on the M4. I need to find a station that is outside the congestion charge zone that has a car park available all day or 24 hrs and takes me straight into london without a massive stress. I am not sure if Park and ride schemes are available etc but I need all the help I can get so hopefully someone can help. I am not sure if there is a station more south if I travelled the old road to London from Exeter of the above roote. Please help!!!
