I'm going to have the entire summer for the trip over 8 weeks. I want to have everything planned out are ready to go for June 28. I want to take my time and have a great summer with the kids. We're going to travel the trans canada highway on the way there and come back through the northern states on the way home. I want to be flexible and have a schedule (crazy right). I'm going to plan on 2 weeks to get there (10 days if I do 400km/day (250 miles) and use the rest of the summer getting back.
Yellowstone only adds 2 days to the trip home so a stop there could be fun.
I know I'm probably over thinking this but I don't think I'll ever get this opportunity again and want to make the most of it.
I just tried microsoft streets and trips and it seems a little too rigid when I put in 4 hours of driving it uses 4 hours exactly even when I added 2 hours to the flexibility when I noticed it would stop in strange places.
