Exceptional Customer Service from Hana ❤️

There wasn’t really an option to indicate that my review was not about the trip itself, but rather about the customer service, especially Hana. Hana was incredibly helpful throughout the entire planning process. She was always kind, responsive, patient and willing to help, and I really appreciated how much time and effort she put into understanding what I was looking for and helping me plan my trip. I’m very grateful for all her help, and I hope that one day I’ll actually get the chance to travel with you! 😊

Kate Q · February 2026

Amazing and varied trip

From our first contact with Asia King, the service was excellent. Miss Chu Hanh (Hana) created a varied and busy cultural tour for us. We stayed in 5 hotels, had 3 internal flights, 5 guides who were all fantastic and interesting and 5 drivers with whom we felt confident. The hotels were 4 star and what we expected. We loved it all.

Response from the operator: Thank you for your kind words about our team. We hope you have a wonderful trip!

Tour of Vietnam and Cambodia

The level of service from Hana at Asia King was exceptional. She was very attentive and went out of her way to help prior to and during the trip. I would thoroughly recommend using Hana at Asia King.

A Special Experience through the Mekong.

I had a wonderful time on the tour through the Mekong River. Everything went smoothly. The people at King Travel made sure all the details were taken care of. They were very professional and also showed great caring. The service on the Mekong Princess was excellent as well as the food. The itinerary they prepared was very well thought . There was always an activity related to the area where we were. I enjoyed every single one of them. I have been on many river cruises; to me this was a very special one.

12 Day Cross Vietnam and Siem Reap Tour: questions travelers ask

Practical detail on this experience, plus the wider planning questions for Hanoi.

How much does 12 Day Cross Vietnam and Siem Reap Tour cost?

+

Prices start at $1,335 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 12 Day Cross Vietnam and Siem Reap Tour take?

+

Plan for about 288 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 12 Day Cross Vietnam and Siem Reap Tour worth it?

+

It holds an Outty Ranking of 62 out of 100, which we label "Solid Choice". That score blends traveler sentiment (5/5 across 3 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 12 Day Cross Vietnam and Siem Reap Tour?

+

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 12 Day Cross Vietnam and Siem Reap Tour suitable for kids and families?

+

Yes, all ages are welcome. Families should still weigh the 288-hour running time, and strollers are easier on the earlier, quieter departures.

How far in advance should I book 12 Day Cross Vietnam and Siem Reap Tour?

+

Around 1 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 288-hour experience runs outdoors or after sunset.

Where does 12 Day Cross Vietnam and Siem Reap Tour 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 12 Day Cross Vietnam and Siem Reap Tour?

Not included: Gratuities; Early check-in or late check-out; FLIGHTS: Hanoi - HCMC: 180 USD/person. HCMC - Siem Reap: 360 USD/person; and Meals (other than mentioned in the program).
