I’m so glad you found it helpful. Have a great trip!

There are buses on this highway every day of the year in all weather conditions with very few issues. Winter tires are not required after March 31. In April you may encounter heavy rain with water pooling and possible hydroplaning. However, it’s not likely – just a few days a month in spring. I would recommend using a local bus driver who is familiar with the route if possible. Otherwise, just go slow (buses do this anyway) and be sure to pull over to let other pass in the areas with passing lanes.

You’ll need to book the rental car far in advance – those sell out in July. If your schedule is flexible you may be able to wing it a bit and book last minute but you’ll need a flexible budget and a flexible attitude about where you stay as well. Some small towns have limited accommodation so if its full, you might have a bit of a drive to the next place. Or you might have to be content with paying a ton for a high end place. Or you might end up in very basic accommodation with shared bathrooms (like at some older B&Bs). I wouldn’t recommending winging it when it comes to accommodation, but I think with some flexibility, it’s possible. If you can book things a day or three in advance rather than the day of. Have a great trip!

If you have limited time, the city tour with McCarthy’s Party is the way to go. It hits all the highlights.
