If it is hard to get to Cranbrook, you could consider coming through Calgary if it is easier to get a bus that way. Athough it is a much longer drive there are likely many more flights to Vancouver available from Calgary then from Cranbrook, and relatively cheap flights are not uncommon.
Driving to Vancouver is an option, and Highway 3 which is the shortest route from Fernie to the coast is quite slow and twisty – although not by UK standards (I’m guessing that’s where you are from by your spelling…). The scenery is spectacular if you are traveling during the day. If you are traveling at night, be sure to watch for large windshield height mammals (e.g., Deer, Elk) appearing out of the darkness when you least expect them.
The biggest problem with driving at this time of year is the possibility of nasty Winter driving conditions and road closures. If your plans are flexible enough to allow you to wait out any storms this might be a good option. With luck the roads will be clear if you choose to drive, but the potential for poor driving conditions should not be taken lightly, especially if your schedule is tight.
