One person doing the driving.
How long do you think is ok to plan for one days driving? 4 hours? 6? 8? 10?
Holidays, not work related. And is it reasonable to suggest DH drives a long distance alone because it would be convenient for me (and mean he wouldn't have to spend a week visiting my family). Then we share the return journey between us and do some sightseeing on the way back over 2-3 days. For full disclosure, I am not a fan of driving and prefer to take a break after an hour- hour and a half. DH likes driving so tends to do more in every day life.
