I have to drive from Retford (DN22) to Heathrow, arriving at Heathrow for 9am (!!!!!!!!!!!!!!!!!!!)
Satnav gives the journey as around 2 1/2 hours, but clearly it will be a bit longer than that......can anyone advise how long I should allow at that time of day?
One thought would be to leave early (4am ish) to avoid the M25 carpark, but I like my sleep, so might be tempted to lie in a bit longer if I could judge the timing right.
Thanks in advance.............
