Seeking suggestions --
Flying to Denver - Wanted to take a round trip back to Denver; Have 7 Days -- Just me n my wife (leaving the little one with Grand Parents)
Thinking off Yellowstone Natl Park; Glacier Natl Park; Banff National Park; Lake Louise and back to Denver.
I know 7 Days is too short, but my initial idea was to just drive around(I have plans to visit Yellowstone again during winter 2013).
Having said that - can anyone chime in where should i spend more time and what can be skipped?
Also how do the US Car rentals (Hertz) work in canada? Do i have to be up front about it?
