What it costs, line by line, and what a cheaper quote left out

Where a day rate actually goes

These are the supplier ranges behind the two columns above, drawn from what the same rooms, cars and guides cost across the 2026 season. Hotel figures are per room per night; a room holds two people, so halve them when reading a per-person day rate. Vehicle and guide figures are per party per day, so a group of six divides them six ways and a couple divides them two.

Reading the table

Hotels are the largest single line and the one with the widest spread. On the Comfortable standard a room in Hanoi, Hoi An, Siem Reap or Luang Prabang sits in the low hundreds; on the Excellent standard the same night can be a room at the Sofitel Legend Metropole, Amantaka, the Four Seasons The Nam Hai or Amansara, and the Cambodian top of the range is high because Siem Reap holds one of the most expensive small hotels in the region. Any of those names is an example of a standard, never a guaranteed inclusion — the quote you receive names the property actually held.

Guides and vehicles are the line that party size acts on hardest. A national guide at USD 120 a day is USD 60 per person for a couple and USD 20 per person for a group of six, for identical work. Four countries means four guides and four cars, each licensed and registered where it operates; there is no version of this where one guide follows you across three borders, and there is no version where a driver in Vietnam takes you into Cambodia.

Flights are what the closed Thailand–Cambodia border turned from optional into structural. Bangkok to Siem Reap is about 1 h 15 and Bangkok to Phnom Penh is similar; Hanoi to Luang Prabang is 1 h 10, Siem Reap to Luang Prabang 1 h 25 on five days a week, Siem Reap to Ho Chi Minh City about 1 h 10, and Hanoi to Siem Reap about 1 h 50. Each sector adds its fare plus two transfers, and Siem Reap–Angkor International sits 40 to 50 km from town, so the transfer is 45 to 60 minutes rather than fifteen.

Boats sit apart from everything else. A Lan Ha Bay cabin is a hotel room that moves, priced per cabin per night, and Lan Ha carries far fewer boats than the Ha Long core, which is why we use it. A Mekong ship cabin between Siem Reap and Ho Chi Minh City is a different order: seven nights runs from about USD 3,879 per person at the Pandaw end of the market up to roughly USD 9,000 on Aqua Mekong, and that single line can carry a third of a fifteen-day journey.

Entrance fees are small individually and add up steadily: an Angkor three-day pass at USD 62, the Bangkok Grand Palace at 500 baht, Wat Pho at 300 baht, Hue Imperial City at 200,000 VND with royal tombs at 150,000 VND each, and the Hoi An old-town ticket at 120,000 VND, which admits you to five of twenty-two heritage buildings. All of them are inside the price we quote.

The four variables that move the price, ranked

1. Party size — the largest single lever

The car, the driver, the guide and most permits cost the same whether two people or six use them. Going from two travellers to five or six takes roughly 22 per cent off the per-person day rate on the Comfortable standard and roughly 22 per cent off the Excellent standard, without touching a hotel or removing a day. Nothing else in this list moves the number that far. If a friend or a set of parents is a real possibility, ask before you fix the itinerary rather than after.

2. Season

Mid-November to early February is peak across all four countries at once, with late November to mid-January the sweet spot, and hotel rates in that window run 15 to 40 per cent above the same room in May. Christmas and New Year are their own tier: many properties in Siem Reap, Hoi An, Luang Prabang and on Koh Samui impose compulsory gala dinners on 24 and 31 December, typically USD 90 to USD 250 per person, and those are contractual rather than optional. Travel in late February or early March and the same journey costs noticeably less — at the price of heat building at Angkor and smoke arriving in the north.

3. Hotel tier

The step from Comfortable to Excellent adds about 54 per cent to the day rate, and almost all of it is the room. It buys a different address, a different room size and a different breakfast; it does not buy a better guide, a shorter drive or a different temple. Parties who care about where they wake up should take it. Parties who care about what they do that day should stay on Comfortable and spend the difference on days.

4. How many internal flights the route needs

Each sector adds a fare of USD 90 to USD 320 per person plus two transfers and a half-day of movement. A route with two flights and a train is cheaper and calmer than a route with five flights, which is one reason Vientiane to Luang Prabang goes by rail at 1 h 50 rather than by air, and why the four-country journey needs twenty-eight days rather than twenty-one. Cutting one flight from a route usually saves more than downgrading two hotel nights.

What the price does not include, and why

• International flights into and out of the region. Fares from Europe and North America move by hundreds of dollars depending on when you book, and building a guess into a land quote hides that from you rather than helping.
• Visas and the three digital arrival cards. Vietnam runs an e-visa open to all nationalities for up to 90 days, with a 45-day exemption for 24 countries; US, Canadian, Australian and New Zealand passports get no exemption and must hold an e-visa. Cambodia is USD 30 plus USD 6 processing for a 30-day e-visa at evisa.gov.kh, about three working days. Laos issues a 30-day visa on arrival at roughly USD 30 to 45.
• The arrival cards themselves are free and must be filed by the traveller: Thailand’s TDAC within 72 hours of arrival at tdac.immigration.go.th, Cambodia’s e-Arrival within seven days at arrival.gov.kh, and the Lao LDIF, mandatory since September 2025. Sites charging a fee for any of the three are not official ones. Note also that Thailand’s visa exemption drops from 60 days to 30 on 15 September 2026, with one extension of up to 30 more days available at Thai immigration.
• Travel insurance, which we require rather than sell. Ha Long and Lan Ha ports close outright on storm warnings — a tourist boat capsized on 19 July 2025 during Tropical Storm Wipha, killing at least 37 people, and cruises were suspended for a safety review. A route through the bay needs both a buffer day and a policy.
• Tips for guides and drivers. These are yours to set, and the final pack gives the local range rather than a number we collect.
• Most lunches and dinners. Breakfast is in every hotel rate and a few set meals are included where there is no alternative — on a cruise, on the river, on a long transfer day. The rest is left out so you can eat where you want at the price you want, which in Hanoi or Chiang Mai is often the best meal of the trip.

How a quote 25 per cent cheaper is usually built

Cheaper quotes are rarely dishonest on their face. They are assembled from six substitutions, each defensible on its own, and the sum of them is a different journey wearing the same itinerary title. Read any competing quote for these six things specifically.

1. Guide days quietly dropped. The itinerary still says Siem Reap, three nights. It no longer says a guide on all three days. Two of them become a driver and a ticket, and the difference is USD 90 to USD 150 a day that never appears as a deletion because it was never itemised.
2. Hotels described by star rating rather than named. "Four-star centrally located" covers a range of about USD 130 per room per night in every city in this region. A named hotel can be read, reviewed and located on a map before you pay; a star rating cannot, and the property is usually chosen after your deposit has cleared.
3. A shared shuttle instead of a private car. The word "transfer" hides both. One waits for you; the other waits for eleven other people and takes the route that suits them. This substitution is most common on airport legs, where it costs you an hour at each end.
4. A 46-cabin boat sold with the same words as a 12-cabin one. On Ha Long and Lan Ha, and on the Mekong, cabin count is the fact that changes the experience and it is the fact most often left out. Ask for the ship name and the number of cabins, then look it up.
5. Commission stops written in as local craft experiences. The gem workshop, the silk village, the lacquer factory and the jewellery showroom pay the operator a percentage of what you spend. Two of them in a day removes a morning from your itinerary and adds nothing to the quote you were shown. None appear on ours.
6. The Bangkok to Siem Reap leg shown as an overland day. That crossing has been closed since 23 June 2025 and Thai authorities have said there is no plan to reopen during 2026. A quote that still prices it overland has either not been updated or is relying on you not to check — and the flight it will be replaced with costs money that is not in the number you are comparing.

Put those six back into a cheaper quote and the gap usually closes to within a few per cent. Where it does not close, the other operator may genuinely be cheaper, and we will say so.

Payment and cancellation

A 30 per cent deposit confirms the journey and releases the hotel, flight and cruise holds. The balance falls due 45 days before departure. Refunds step at 90, 60 and 45 days because that is when supplier money leaves — cruise cabins and the better rooms in the mid-November to early February window are paid down long before you fly. The exact ladder is printed in the quote you sign, and the booking steps set out the sequence.
