In reply to Hans:
Where abouts are you planning to stay?
It's been second winter in a row when I hitched from Glasgow to Fort William or Glen Coe to stay in a hostel. After sorting myself out, I just start hunting for people who look like climbers, hill walkers, etc. Never needed to take a bus or walk, always had a ride in the morning and sometimes I even got a buddy to climb with. Or at least you might be able to find someone who would accompany you to the CIC Hut and then you can split. That walk-in is not fun, even if the path is in decent nick.
Smaller hostels like Glen Coe Independent Hostel helps. Or maybe it was because of the fact that there was only one tourist and all others were outdoorsy people.
