So I need to get to Cornwall and back in one day to pick someone up. It's a 3hr drive on a good day so that's 6+ hours plus traffic and breaks whenever I feel knackered/need a coffee and a leg stretch. I plan on leaving very early AM to avoid rush hour traffic (it'll be midweek at least) and coming back either midday or after the evening rush hour traffic (partly just so I can gather myself a bit before doing the return journey too)!
I've driven there one way and it's fine with breaks etc...
