We had an amazing trip in Busan and Gyeongju. Katrina and Vivien were both our Chinese and English-speaking tour guides. Katrina was very patient, friendly, and knowledgeable. She explained the history of Gyeongju in a very interesting and easy-to-understand way. We learned so much throughout the tour. Vivien was also very helpful and attentive, making sure everyone was comfortable and enjoying the trip. Thanks to both of them, the tour was smooth, enjoyable, and memorable. Highly recommended!
