Hi We will be flying into Vancouver in early September and spending 4 nights. At this stage we plan to fly from Vancouver to Calgary and hire a car to drive direct to Banff spending 3 nights. Drive to Jasper for 3 nights then 1 night in Lake Louise before driving back to Calgary for flight to Vegas that evening. I have 1 extra night and not sure where to spend it and would appreciate any suggestions. Do we add an extra night to one of these locations or is there somewhere in between that we should consider? We enjoy scenic easy to moderate walks, sight seeing, nature, culture, eating and drinking!
