Write to us, and get a real answer
One office, two numbers and two email addresses, all listed below. Below them: how long a reply takes, what to put in a first message so the quote you get back is worth reading, and which channel to use once you are on the road.
Our office
Planning, quoting and accounting happen here. Guides and drivers work out of the cities on your itinerary.
Hanoi, Vietnam
08:30 - 18:00, Mon - Sat (GMT+7)

Phone, WhatsApp and email
The first number and the first address are for planning a trip. The second number is the line for guests who are already travelling, and it is staffed around the clock by someone who can open your itinerary.

New enquiry or a quote in progress: email, or WhatsApp if you prefer to type quickly. Already on the road: the 24-hour number, by call rather than message, because a phone that rings gets answered faster than an inbox that fills.
How long a reply takes
These are working targets, not a promise carved in stone, and we will tell you when we are going to miss one.
| What you sent | You hear back within | What arrives |
|---|---|---|
| First enquiry | 1 working day | A named planner, any questions we need answered, and a rough price range |
| Enough detail for a quote | 2 working days | A day-by-day outline with an itemised price |
| A change to a quote in progress | 1 working day | The revised lines, with the difference shown separately |
| A message while you are travelling | Immediately, by phone | The person on the 24-hour line, with your itinerary open |
Saturdays count as half a working day here. Sunday messages are read but rarely answered the same day, unless you are travelling.
What to put in the first message
You will get a usable quote from the first reply, rather than a request for more information, if the message contains these six things. Two lines each is plenty.
- Dates, or the month. Fixed dates are best. “Second half of February, flexible by a week” is almost as good.
- How many of you, and ages if children are coming. Group size moves the per-person price more than anything else on the list.
- How many nights you have on the ground, not counting the flights in and out.
- A budget per person per day for land arrangements, or a total. A range is fine. Without it we guess, and a guess wastes a round.
- Two or three things you refuse to miss, and one thing you would rather avoid. The second half is more useful than the first.
- What standard of hotel you sleep well in. Say it in plain terms: simple and clean, good four-star, or the best in town.
If you are not sure what a realistic budget looks like, read the pricing page first and quote a band from it. That single line usually saves a week of back-and-forth.
Office hours, in GMT+7
Our working day is 08:30 to 18:00, Monday to Saturday, Hanoi time. That converts to the hours below during European winter; when your country is on summer time, subtract an hour from your local column.
| Where you are | Our 08:30 is | Our 18:00 is |
|---|---|---|
| London | 01:30 | 11:00 |
| Paris and Berlin | 02:30 | 12:00 |
| New York | 20:30 the day before | 06:00 |
| Sydney | 11:30 | 21:00 |
A message sent from Europe in the evening is read here the next morning, so the answer is usually in your inbox before you wake up.
While you are on the road
Every travelling guest gets a single in-country number, printed on the front of the final documents and saved to your phone at the airport meeting. Use it for anything that needs to change today: a flight moved, a driver not where you expected, a stomach that has given up, a hotel room you want swapped.
For anything that can wait until tomorrow, message your planner instead. They see it at the start of the Hanoi working day and can move the rest of the trip properly rather than patching one afternoon.

Common questions
Questions travellers ask most
Do you take phone calls before I have booked?
Yes. Send two or three times that suit you with your time zone, and your planner will call. We ask for a written outline first so the call is about decisions rather than spelling out place names.
Is WhatsApp answered as quickly as email?
During Hanoi office hours, faster. Outside them, email is safer, because a WhatsApp message sent at midnight our time can sit under later messages. Anything about money or dates we confirm by email regardless of where the conversation happened.
Can I visit your office?
You are welcome to, with a day's notice so the right planner is there. Most people who are already in Hanoi prefer to meet at their hotel, and we will come to you.
Do you charge for planning or for a quote?
No. Planning is free until you accept a quote and pay a deposit, including the revisions, which usually run to two or three rounds. The booking page explains what happens after that.
