My partner and I booked the night before and were the only two people on the tour. We got the recommendation from a different tour guide (Tam) and booked directly through the Hoi An Express site.
Snow is super funny and very knowledgeable about Vietnamese history. We stopped at Hai Van Quan and saw the fort remnants and lookout. In Hue we took a dragon boat to the Thien Mu pagoda and then headed to the Imperial City. Snow taught us a lot about the emperors of Vietnam, especially the penultimate emperor, Khai Dinh. We had a lovely set lunch near the imperial city, saw the resting place of Khai Dinh and headed back to Danang.
I thought this tour was 5-stars because Snow provided such a rich history of Vietnam, its rulers, the French, etc. She was also hilarious. Good laughs and good times were had.
