When planning this kind of route, we tend to start by mapping out driving days of 3 hours or less. We then take that number of stops and double it, figuring we only want to drive half of the days. The first route came out to 30 stops, which would be doable in 60 days. We've got 68 to do it. That's a reasonable average of 66 miles a day.
Now, once we're sure it's doable, we'll actually try to fit it all on a calendar, assigning a few more days here and there for places we really want to see and knowing that we'll tend to string driving days together at other times. For this route, we gave some extra time to Jasper, Banff, Glacier, Bozeman, Yellowstone and the Tetons. Along the rest of the route, we'll just have to borrow rest days as needed when we find a place we'd like to stay longer!
And as always, we'd love to hear from anyone who might be along our route or who has recommendations on things we should definitely see (or avoid!).
