Three generations, one week.

Who is actually travelling

The standard group we handle is six to nine people: two grandparents, sometimes only one, the parents, one or two children, and often an ayi or nanny who has been with the family for years and who does more of the real work than anyone else on the trip. These people want different things and have different limits, and the mistake almost every family makes is planning the trip for the middle generation, who are the fittest, the busiest and the ones holding the credit card. The itinerary that results is thirty percent too fast for the grandparents and thirty percent too slow for a nine-year-old.

The fix is not compromise, which produces a week nobody enjoys. It is two or three parallel programmes sharing a base, a breakfast and a dinner. Everything here follows from that.

Pacing: one thing a day

The single most useful rule we give families is one fixed commitment per day. One temple, or one market, or one boat, or one lunch out. Not two. Thailand is hot and humid in a way that a fit fifty-year-old registers as pleasant and an eighty-year-old registers as an ordeal by eleven in the morning, and heat exhaustion in an elderly traveller does not announce itself politely. The productive hours are before ten and after four, and the middle of the day belongs to the hotel, the pool, the room, a long lunch and a nap. Families who build the week this way come home rested. Families who schedule morning and afternoon activities spend the last three days managing an unhappy grandmother and a tired child.

Build in a genuinely empty day around day three or four. Long-haul travel, even a five-hour flight, catches up with older travellers on the second or third day rather than the first. And keep arrival and departure days empty; the temptation to add a dinner on arrival night is the temptation to start the trip badly.

Food, and the breakfast problem

Breakfast is where a good trip is won. The international breakfast buffet at a Bangkok five-star is enormous and will still leave a seventy-five-year-old from Hangzhou looking for congee. The good hotels have Chinese breakfast items, but the depth varies wildly and the congee at the end of a buffet is not the congee at home. We ask three questions of a hotel before booking a group with elders: is there congee with proper condiments every morning, can the kitchen provide hot soy milk and steamed buns, and can they put a kettle and a thermos of genuinely hot water in each room. That last one matters more than any feature in the brochure, and the hotels that understand Chinese guests provide it without being asked.

For the rest of the day, Thai food is easier for Chinese palates than most cuisines, with two adjustments. Chilli levels in restaurants serving locals are high, and the phrase for not spicy needs to be said clearly and then confirmed. And cold drinks with ice, raw salads and cut fruit from the street are the usual sources of an upset stomach. Grandparents in particular should stick to hot food, bottled or filtered water, and fruit peeled in front of you. Bangkok has excellent Cantonese and Chinese dining in the hotels, with long-running rooms such as Shang Palace at the Shangri-La and Mei Jiang at The Peninsula, and Yaowarat's older banquet houses are worth one evening. Booking one familiar Chinese dinner every second or third night is not a failure of adventure; it is what keeps the elders eating properly.

Medical comfort

Thailand's private hospitals are one of the real reasons multi-generational Chinese families choose it, and they should be part of the plan rather than an emergency discovery. In Bangkok, Bumrungrad International, Samitivej and the Bangkok Hospital group all run international departments with Mandarin interpretation, appointment desks that will see a walk-in the same day, and standards that will reassure any family used to a good mainland tier-three hospital. Phuket and Chiang Mai have their own private centres. Before the trip, we note the nearest hospital to the hotel, its address in Thai for the driver, and the number, and we put all three in the family group chat.

• Carry all regular medication in original packaging with the prescription, in hand luggage, in quantities that cover the trip plus a week.
• Check any medication against Thai controlled substance rules before travel; some common items require documentation and a few are restricted.
• Take travel insurance that names private hospital treatment and medical evacuation, and check the upper age limits, which often exclude the very travellers who need cover.
• Bring a written summary of each elder's conditions, allergies and current drugs, in Chinese and English.
• Pack for the heat, and note that air conditioning set to sixteen degrees is its own health risk for older travellers.

Rooms, and how they should be configured

The configuration question is the one families most often leave to the hotel, and hotels optimise for their inventory rather than for your grandmother. Grandparents should be on the same floor as the parents at minimum, and ideally in a connecting or adjacent room, confirmed in writing rather than requested at check-in. Twin beds rather than a king are frequently what an older couple actually sleeps in at home, and nobody asks. A bathtub with a high side is a hazard; a walk-in shower with a grab rail and a non-slip mat is not a luxury request. Ask for a room near the lift rather than at the end of a long corridor, and check that the route from lift to breakfast is step-free.

For groups of seven or more, a two-bedroom or three-bedroom suite, a hotel residence or a staffed villa usually beats a row of rooms. The shared living space is where a multi-generational trip actually happens: cards after dinner, the children doing homework, the grandparents watching something while the parents talk. A villa with a private pool solves the middle of the day entirely, and in Phuket or Koh Samui it costs less than the equivalent room count at a resort. If the family travels with its own ayi, she needs a proper room, and this must be specified at booking rather than negotiated on arrival.

The parallel programme

Two logistical pieces make the parallel programme work. The first is enough cars: one vehicle for nine people means everyone moves together whether they want to or not, and a second car with its own driver is the cheapest freedom you can buy in Thailand. The second is a guide who understands the group rather than the itinerary, who will take the grandparents back to the hotel at eleven without it feeling like a defeat, and who speaks Mandarin well enough that the elders are talking to a person rather than being managed.

Airports and transfers

Suvarnabhumi is a long airport, with walks between gate and immigration that surprise people. Order wheelchair assistance for any elder who cannot comfortably walk a kilometre, and do it at booking rather than at the gate; it is free, it is well run, and it also moves the whole party through immigration faster. On the ground, use a vehicle with a low step and a real luggage bay rather than a stylish SUV, brief the driver on the hospital as well as the hotel, and give the family a fifteen-minute buffer at every departure, because a group of nine has never once been ready on time.

What we brief ahead

For a family of this shape our office sends the hotel a single page a fortnight before arrival: the rooming plan with connecting rooms named, the mobility notes, the dietary lines including anything the elders avoid, the congee and hot water request, the birthday or anniversary falling in the week, the ayi's room, the car plan, and the hospital we would use. Hotels of the standard we book do all of it well when they know a fortnight out, and improvise badly when they learn at check-in. The family's only job is to tell us the truth about who can walk how far.

Medication rules, wheelchair assistance procedures and hospital admission requirements vary; check controlled substance rules with the Thai Food and Drug Administration or the Royal Thai Embassy before travelling with prescription medicines, confirm assistance with your airline at booking, and confirm insurance age limits and hospital coverage with your insurer in writing.

This briefing is general information, not legal, tax or investment advice. Thai rules change frequently and individual cases differ. Verify current requirements with the relevant authorities, including the Immigration Bureau, the Board of Investment, the Land Department, the Department of Business Development and the Revenue Department, and take advice on your own facts before acting.
