The tour guide was very attentive, repeatedly confirming the pickup time the day before. On the day of the tour, they even let you know when they were arriving soon or would wait for ten minutes, which made it easy to manage your time. During the trip, it was a small group combined with Vietnamese tourists, which was unique because I thought they would understand the historical background or could just read the text descriptions. However, the tour guide was very skilled at continuously switching between Vietnamese and English, although sometimes some of the sounds were hard to understand. But they would use very simple words to explain, which allowed you to infer what they were saying. The whole itinerary revolved around the Imperial City and temples, and each time there was 15 to 30 minutes of free time. I think it would be perfect if you signed up with friends and wore Ao Dai or royal clothing, because the scenery is stunning, and there aren't too many people, so you can take beautiful photos of each other, except that it might be really hot and you might sweat a lot XD.
