We are an Australian family planning a trip to Alberta in mid November. We are undecided about whether to fly to Edmonton or Calgary(from Vancouver) or catch a train to Jasper. We want to see Jasper, Lake Louise, Banff and are still debating Edmonton (other than the mall we are not sure what else to do there). We are planning to hire a car and want to know is there an advantage in hiring a 4WD car when travelling in the mountains and considering the time of year? Hiring a 4WD is quite expensive but if it is safer we would be prepared to do so.
