Additionally, you are going to want to do the Jasper to Lake Louise drive during the daytime, so if you don;t stay two nights in Jasper, you would essentially be driving to Jasper, sleeping, waking up, and then driving to Lake Louise, which would be pretty pointless.

Highly recommend you stay at the Fairmont's along the way.
