The current dilemma is whether I should take 5 days (as I did in August) or 6 (as Janelle did in September). I'm currently leaning towards the five day option.
The five day option means three days of driving around 15 hours or more in a day. While I've done that before, this time I have the benefit of another driver who could give me driving breaks from time to time while we still made forward progress. Two of those long days are through the parts of Canada that are (to me) extraordinarily dull. The five day option also means that I won't have to drive on Sunday (something that I prefer to avoid). More importantly, it means that I will be home an entire day sooner.
The six day option gives me more time each day for the drive. I may need that since I will be driving a loaded rental truck rather than the loaded Prius that I took last time. I also won't be quite as tired when I get home (although that was more of an issue last time as I had to be to work the morning after I arrived).
I need to make the decision soon so I can make certain I have hotel reservations for the duration of the journey.
