Odynovo tours : I would like to thank all of our tour guides and drivers from Odynovo who made our Asia trip wonderful
This tour we were pampered by all of our drivers and tour guides from our time in Vietnam with Guide name’s : NGUYEN DUONG NGHIA Driver : NGUYEN QUANG TRUNG VInh Vo Hong & Son in Hue as well Ben in Ho Chi Min then Sakada in Cambodia , Jackie and thon as well as Nick & One in BangkokThey were all amazing and so helpful and accommodating, from being picked up at the airports and taken to our hotels , the little extras like ice cold water and ice cold towels to wipe off after being in the hot weather exploring all the different locals , to helping barter at markets so we didn’t overpay and most took us not only to the airports but right to where we were supposed to go , as some airports are quite large that was a really nice touch . All the sites were amazing and the people very friendly. The food throughout our trip was fantastic as well as all the recommendations for restaurants to eat at from our guides . It truly was a trip of a lifetime for our family and just wanted to say a heartfelt thank you The Dunn family

Family holiday with Authentic
Our family of four travelled from Sydney to Asia on a 23 day tour with Authentic adventures. Our tour organiser, Tran was amazing and so helpful from the planning stage right throughout the whole trip, he was available at a moment notice and we had the pleasure of meeting her in Hanoi. Everything was organized for us and any hiccups, like flights delays, Tran was on to it immediately to adjust pick ups etc. The accommodation and meals provided were excellent and the price we thought very reasonable. I would definitely use Authentic again and recommend.
Response from the operator: From Authentic Adventures Vietnam, What a fantastic review! We're delighted that our tour left a lasting impression on you. Your satisfaction is our priority, and we can't wait to welcome you back! Best regards

Thank you!
I arranged for me and my family the Vietnam, Cambodia and Thailand with Authentic Adventures. Everything was perfect from the first contact when I found this agency in Internet. Good communication, clarity of the trip arrangements, guiding and pick up/transfer services. Special thanks to our consultant Tran - who took care for us from the very first beginning. Tran helped us when we had to change the travelling agenda due to weather conditions. Great, perfect contact via WhatsApp, SMS or phone. @Tran, thank you for all your efforts.
Response from the operator: From Authentic Adventures Vietnam, We're thrilled to hear that you had an amazing time on our tour! Your satisfaction is our mission, and we're grateful for your kind words. See you again soon! Best regards

Why this scores 69
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Southeast Asia 23-day: Vietnam, Cambodia & Thailand: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Hanoi.
How much does Southeast Asia 23-day: Vietnam, Cambodia & Thailand cost?
+
Prices start at $3450 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 Southeast Asia 23-day: Vietnam, Cambodia & Thailand take?
+
Plan for about 552 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 Southeast Asia 23-day: Vietnam, Cambodia & Thailand worth it?
+
It holds an Outty Ranking of 69 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 20 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 Southeast Asia 23-day: Vietnam, Cambodia & Thailand?
+
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 Southeast Asia 23-day: Vietnam, Cambodia & Thailand suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 552-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Southeast Asia 23-day: Vietnam, Cambodia & Thailand?
+
Around 7 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 552-hour experience runs outdoors or after sunset.
Where does Southeast Asia 23-day: Vietnam, Cambodia & Thailand 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 Ninh Binh Day Trip from Hanoi with Tam Coc or Trang An & Mua Cave, Ha Giang Loop Tour 4 Days 3 Nights with Ha Giang Vision Tour, Halong Bay Day Tour With Titop Island, Cave, Kayak & Lunch. 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.
