Planning to visit the Louvre Museum, a must-see for anyone's first trip to Paris, I applied for a tour, thinking that I could gain a deeper understanding and have a more enjoyable museum exploration with the guide's explanation. Exploring the museum with Royal Ji-sung, I received detailed explanations of works that I would have otherwise missed, allowing me to appreciate their meaning two or three times over. I lost track of time and the tour was truly meaningful and satisfying. The Louvre can take 3-7 days to see properly, but with the author, I was able to explore the key elements and have a fulfilling 3-hour tour. Highly recommend it.
