LOL! Yeah, I'd say 8 hrs is a bit unrealistic, but we did Wick to Leeds thru the night last year* & if we have a similar trip I reckon 9 or 10 is just about possible. :^) Doesn't really matter if it takes the 12 hrs the AA reckon, anyway....
*Only hairy moment was a stag on the A9. Not a Triumph Stag - a girt big hairy & antlery one.
Don't wanna wait 'til July now! ;^)
