Thumbs up to Mr. Duke Nguyen for our wonderful tour from Hanoi-Danang and Saigon. I thank him for accommodating all my questions and concerns while preparing our itinerary. Since we were traveling as a group , I honestly told him about our limited budget and after several changes, he really gave us a package which suits our needs. Thanks for your patience, Mr. Duke! Aside from 1 driver who brought us to the wrong airport and one tourist who hated people laughing, everything was at its best! The Halong bay tour was the most wonderful – the scenery and the super delicious food were more than enough. Credit to Mr. Kien, our tour guide who was very professional, witty and very eager to help us with our picture taking! ( 5 star for this guy !). The Cu Chi tunnel tour was very informative. Thanks to our tour guide, Mr. Long for the narratives about Vietnam history and for accompanying and showing us the best side trips (shopping trip !) in HCM. Mr. Duke is very quick in responding and would utilize all possible communication channel – PM, email, WhatsApp - just to keep me posted. I am thankful for his quick reply all the time .( saved me and my friends from not being able to fly on time with the wrong airport at 4 .a.m)… I would definitely book with VAC travel again and would recommend Mr. Duke to my friends.. Thank you again and again. We had a great time in Vietnam. ( by the way, Vietnam is 1 hour late than Philippine time! Lol)
