We are planning to do a week in the Canadian Rockies next summer and wanted some advice on how long to stay where. The only definites are: we are flying in to Calgary, staying the weekend and then off to Banff/Lake Louise. Do we need 2 or 3 days there (we love hot springs!)? Also wanted to see Jasper. Then drive to Edmonton for the following weekend and fly home. Worried about drop charge for the rental car or should we just drive back down to Calgary (hwo long and is it scenic)? Thanks for your help!
