Scotland - Ben Nefis

So I'm going to Scotland on Saturday with a mate of mine, we're gonna climb up Ben Nefis (mountain). I even have a little Welsh flag to put at the top! lolz
So I was wondering if anyone who lives or has been there had any tips about Ben Nefis and the surrounding area?
We're staying in a caravan at the foot of it, the main reason for going is for inspiration to write songs for the band.
And also, we have to travel 8+ hours to get there, so if anybody has any ideas of how I'm supposed to survive the car journey, then please help! lol
Any replies I will +rep if I can.
