Wonderful 18 days / Vietnam, Cambodia and Thailand.
I found Authentic adventures by chance on TripAdvisor while looking for information on trips around Asia, Vietnam, Cambodia and Thailand. They were immediately helpful and kind and thanks to Tran ( my reference person of Authentic) I had an unforgettable journey to Asia. Everything was perfect: hotels, cars, flights and especially drivers and guides.
Response from the operator: From Authentic Adventures Vietnam, Thank you for the glowing review! We're delighted that you enjoyed our tour, and we appreciate your recommendation. Looking forward to your next adventure with us! Best regards

Very good agency!
My husband and I recently had three fabulous tours through Authentic- Vietnam, Cambodia& Thailand. Our guides in each place were great-they were very knowledgeable kept us informed and amused all day. We were very impressed with the hotels they provided us with and found the transport first class. The itineraries were full, but not too tiring and we saw a lot of interesting and beautiful places. We would have no hesitation in recommending them to anyone visiting any of these countries. Thanks so much Authentic adventures!

18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Hanoi.
How much does 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 cost?
+
Prices start at $2,859 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Hanoi usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 take?
+
Plan for about 432 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Hanoi is not rushed.
Is 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 worth it?
+
It holds an Outty Ranking of 68 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 11 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Hanoi, and how flexible the cancellation terms are.
Can I cancel or reschedule 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 432-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27?
+
Around 4 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Hanoi can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Hanoi and add a light layer if any part of the 432-hour experience runs outdoors or after sunset.
Where does 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Hanoi within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Hanoi?
+
On Outty we rank every Hanoi experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Ha Giang Loop 3-Day Small Group - from Hanoi, (Group/Individual) HANOI STREET FOOD TOUR, Incense Village Quang Phu Cau, Hat Village and Hanoi City Tour. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Hanoi?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Hanoi?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
What is included in 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27?
+
Included: Tour guide; All entrance fees for the included sightseeing destinations; Accommodation: Private room; Air-conditioned vehicle; and Lunch. Not included: Tips, Alcoholic drinks, soft drinks, personal expense. Always check the voucher for the final list before you travel.
Does 18-day Itinerary Vietnam - Cambodia -Thailand | Best 2026-27 include hotel pickup?
+
