Something you may want to consider as you head towards Banff:
I assume you'll take Hwy 1 through Golden. They are doing major roadwork on the twisties heading out of Golden and the road is closed a lot of the time. Depending when you go through you may have to detour via Radium. Check the DriveBC website for accurate info. I think they mentioned being open for Thanksgiving weekend last time I looked.
One place I have seen where there are places to stop is off Hwy 93 heading from Lake Louise towards Jasper. If you head north at the Sask Crossing turnoff there are a number of places where you can overnight including a few Government CGs. Not sure on their closing times though.
A lot depends on how far you will go in 1 day too.
