Every time I go to Japan, I book a day trip to some remote attractions through KKDAY. It's so easy to get to the beautiful places I want to visit without any hassle! This time, our guide, Mr. Tian (my Mandarin isn't very good, so I hope I heard correctly! 😜), provided excellent service. He was polite, funny, and considerate. The female driver was also very polite and had great driving skills. Driving on the winding mountain roads, I didn't feel any swaying or jolting at all, and the whole trip was very comfortable.
Our tour guide, Ms. Peng, was very kind and polite, and provided detailed explanations along the way. She also recommended local specialties at various attractions and offered a personal ranking list for reference. 👍 We were incredibly lucky on the day of our trip; the weather changed from cloudy to sunny and then to bright sunshine ☀️ We got to see Mount Fuji 🗻 to our hearts' content! 😆 The other members of our group were also very punctual, boarding the bus on time for the next attraction. 👏 A very happy and enjoyable trip! 💐
Communication was smooth, the driver was very nice, drove very smoothly, and the car was very clean.
