I will honestly tell you that traveling by car is only partly convenient, because you cannot afford to relax, literally at all. When you're on the road, you're always on edge. It's a different matter to travel by bus. This has its own charm, as you can sit back in pleasure and lie down enjoying the views from the window. I recommend traveling with Greyhound. They have excellent customer support
