In reply to Humphrey Jungle:
I've put together some notes here, which may be of use.

( feedback welcome)
Glencoe hobbit houses should defo be open. Kingy is back up and running I think.
Edit: just checked the 3 day suggested overnight spots and its inversnaid & Inveroran.
It * looks* like inversnaid hotel closes for the winter, which would be a pain. Perhaps phone them to check. Which would leave you with Rowardennan or trying to push on to the Drovers if it is open.
If Inveroran is closed then I'd suggest Bridge of Orchy bunkhouse or Hotel. ( can't believe that wont be open).
Or push on to the Glencoe hobbit houses. Pretty easy cycling, but would be a long day if you started withe the Loch Lomond carry....
