Solo woman traveler Vietnam, Cambodia, thailand
I came on this solo trip after having 6+ years of travel experience. I highly recommend using a phone service with data as having internet connection is a must to explore freely and autonomously during your free time on all these countries. All my accommodations were very clean and safe. I was delighted by the quality of service from the staff and the people in general to use Google translate. A word of caution with all the locals is to haggle prices down as you will always get the “tourist” price . In all countries people will not ask for a tip but is appreciated, also google translate is a must, even if they try with some English words; the translator can really help you communicate better. I appreciate David meeting me in person in day 1 and explaining the importance of the itinerary and his follow throughout the trip with active communication. As a solo traveler neither the driver, the groups nor the guide will stay the same for more than one activity, the only constant will be the tour director and the hotline support team when you encounter questions or issues. It was a bit exciting to meet different drivers, tour guides and groups of people for each activity on the program. Very dynamic and interesting. FYI- David Ng is the best tour director!! Always so polite and helpful

Excellent tour made easy by an outstanding tour company
A fantastic tour guide team. Cannot recommend them enough. In a few words!… We did a 22 day tour (that we tweaked) to Vietnam Cambodia , and Thailand- with 6 days added on the end on the sunny east Thai coast. ( if we did again, think we would avoid the one nights in a hotel- opting for at least two). David, from 24/7 was always prompt and knowledgeable with communications or questions, always being beyond helpful, also with suggestions and ideas. He and his team was nothing more than outstanding. Planning a big trip east bound was very daunting, however all fears were very quickly unfounded when in the hands of David. From the minute we landed, prompt, efficient, informative and polite guides & drivers were always on hand. If you’re hesitant- don’t be, we would use Vietnam tours 247 again and again if travelling back to Asia.

Why this scores 65
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Hanoi.
How much does Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days cost?
+
Prices start at $2550 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 Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days take?
+
Plan for about 504 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 Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days worth it?
+
It holds an Outty Ranking of 65 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 7 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 Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days?
+
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 Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 504-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days?
+
Around 2 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 504-hour experience runs outdoors or after sunset.
Where does Ultimate Vietnam, Cambodia & Thailand Tour – 21 Days 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.
