We’ll be staying near St. Pancras, but will rent a car for 4 days to see a little countryside. To avoid the London traffic and a near death experience of driving on the other side, in heavy traffic, right out of the gate we thought it may be worth the tube travel to Heathrow to grab a car there instead of renting one at the train station. We are traveling out of London after dropping it back off, by Eurostar so the train station idea is really easy sounding, except the traffic sounds frightening. (This coming from a former paramedic in Los Angeles.)
So is it worth the St. Pancras to Heathrow- pick up the car- drive around-drop the car back-Heathrow to St. Pancras juggling to avoid the London traffic?
Thank you for any kind of advice. We leave in early November.
