If you're traveling with family, especially with elderly people or children, I highly recommend booking a private car service. You can decide your own travel destinations and stay times, and you can even stop at local supermarkets to buy souvenirs (I bought four large cantaloupes for 7000 yen this time). It was a truly enjoyable and fulfilling trip. Our driver, Mr. Takeda, drove very smoothly that day; I'm very grateful to him.
