Hi, we are coming to North America in late December 2010, and considering our options for a time to visit Lake Louise. We know it would be looking beautiful at this time of year, but what is the prospect of poor weather such as to make access a problem? Our idea has been to fly into Calgary and then either hire a vehicle or do a bus/coach transfer. It is feasible to come into this area on late notice, based on good weather forecasts, and get accommodation, say at Fairmont? We are pretty open with our plans, but they involve Monterey CA, Victoria BC, and Lake Louise. We don't want to come for 3 days and have blizzard conditions.
