Thank you for the information, Sue! That helps, because now I know the names of some of the towns, I can figure out where some good stopping places might be. I'm not familiar with that area at all, so when I was looking at a map, it was hard to distinguish the towns that might have hotels from the small communities that show up on the map.
Since I'm traveling alone, I think I'll try to split it up over 3 days, instead of making the drive in two days. Also, my car is little and only has 3 cylinders and will be filled with my belongings, so if I have to go over a mountain pass, I figure it will be slow going for me.
