In a style that acknowledges the extravagant comforts of early 20th-century travel, Sarah Marshall sips prosecco on a train trip from Bangkok to Vientiane.
The dull thud of hammers on wood disturbs the usual mid-morning peace outside Luang Prabang's Wat Mai temple in Laos.
Teenage monks in saffron robes and jasmine scarves are scurrying around the 19th-century complex carrying long stems of bamboo and banana trunks, the building blocks for a traditional boat.
They're preparing for the annual Fire Boat Festival, in which 2000 boats are sent along Mekong River to mark the end of Buddhist Lent in October.
Rivers may provide one of the country's main transport networks, but my journey here has been by a very different means.
I've arrived in Laos, a landlocked, mountainous country sandwiched between the more popular tourist destinations of Thailand and Vietnam, by train.
One of the poorest countries in Southeast Asia, and governed by a Communist regime, Laos remains off the mainstream tourist track, and links with the outside world have been slow to develop.
The first train linking Thailand and Laos, which crosses the 117km Friendship Bridge from Nong Khai to Vientiane, began running in 2009, and now carries passengers daily.
But our train crossing was something special; we'd arrived a day earlier on the Eastern & Oriental Express.
Regarded as the most luxurious train in Southeast Asia, the younger sister to the Venice-Simplon Orient-Express celebrated its 20th anniversary in 2013.
Our trip from Bangkok into the jungles of northern Thailand and finally into the Laotian capital, Vientiane, is one of the train's Chronicle series of inspiring journeys, designed to introduce travellers to lesser known regions -- all in five-star comfort.
Furnished in exotic elm, cherry, teak and rosewood, the 22-carriage train embraces the gentlemanly grandeur of the early 20th century, when a vibrant expat community of writers and artists took root in Southeast Asia.
Even the fine, diamond-shaped marquetry was inspired by the 1930s' Marlene Dietrich film Shanghai Express, a hit with Orient-Express founder James Sherwood. It's fitting, then, that our visit should begin in Bangkok's prestigious Mandarin Oriental hotel, a favourite haunt of playwrights and novelists Noel Coward and Somerset Maugham.
Bangkok, a sprawling, unkempt city heaving with 13 million residents, continues to pulse with excitement and possibility.
Boats hurry along the Chao Phraya river, carrying tourists to historic temples, or into quiet flower-lined village canals, where locals sell steaming pad thai from long boats in the floating Taling Chan market, and enterprising Buddhist monks sell bags of breadcrumbs to feed long-whiskered catfish.
As we depart for Bangkok's Hua Lamphong Railway Station, the temperature already hitting 34C, I'm reminded of Noel Coward's disdain for Mad Dogs and Englishmen who would brave the scorching equatorial midday sun.
But any madness quickly subsides as we board our grand hotel on wheels, in which a butler has kindly laid out afternoon tea in our private cabins.
Drinking a glass of prosecco from the open air observation car, I watch the steel skyscrapers of Bangkok disappear behind me.
For the next two days, we will visit an ancient Khmer temple (a forerunner to Angkor Wat) at Phimai Historical Park, taste wines produced painstakingly in the Khao Yai jungle, and learn about traditional silk weaving techniques.
From my window, I watch town and country rush past, as local train stations increasingly begin to resemble toy town replicas, decorated with neat flower beds, ceramic animals and the ubiquitous image of reigning Thai king, Rama IX.
Unlike the Venice-Simplon, the Eastern & Oriental provides guests with en suite facilities, meaning there's no excuse not to look glamorous at dinner.
And the menu, devised by French chef Yannis Martineau, is certainly worth dressing up for.
My final breakfast on board this superb train is served as we cross the Friendship Bridge into Laos.
As the first part of our journey draws to an emotional end, we head towards a country where politics have shaped a very different future for its people.
One of the most heavily bombed countries, per capita, in the world (a figure notched up largely during the Vietnam War), it's surprising to discover its people are generally warm, laid-back and remarkably positive.
People here may earn only an average of 40c an hour -- the price of an egg -- but they still find money to throw parties, with speakers tied with ropes to the back of tuk-tuks and crates of state-brewed Beer Lao shared with friends.
This indomitable spirit is most evident in the former royal capital and Unesco World Heritage Site, Luang Prabang, a short plane ride from Vientiane.
The last two nights of our journey will be spent here at Orient-Express property La Residence Phou Vao, with views of jungle-clad mountain upon mountain disappearing into swirling clouds of mist.
Weaving my way through 30 golden temples, interspersed with inviting French bakeries and stalls selling fruit smoothies, it takes me an enjoyably long time to explore the compact town centre.
Sticky rice cakes -- a staple food for Laotians, who can consume 20kg of the stodgy grain in a month -- have been laid out on wire racks to bake in the blistering sun.
Young monks take refuge in the shade -- one studying a Cambridge University chemistry textbook, while another, glad of an audience, shows me how he's taught a small dog to shake his hand.
Sticky rice is fairly tame compared to some of the local delicacies I encounter at the eye-boggling Phousi Market: bowls filled with scaly toads, blocks of congealed blood, and plastic bags of bile used for salad dressing.
That afternoon, I wander down to the riverbank, where park benches overlook the Mekong. I'm joined by a monk, who tells me -- in broken English -- why he likes to come here and "enjoy the nature".
As children splash around in the water below, and the air fills with the smell of cooked meats, lemongrass and sweet frangipani, I reflect on my five-star journey to Laos.
Butler service and comfortable cabin aside, it's being given access to these places, and moments, that's the greatest luxury of them all.
