Four generations, one itinerary.

Count the party properly before anything else

The first document we produce for a large family is not an itinerary. It is a list of everyone travelling, with age, mobility, dietary requirement, who shares a room with whom, and who cannot be separated from whom. It is unglamorous and it prevents almost every problem that follows. A party described on the phone as the family and the children turns out on paper to be a grandmother who cannot manage stairs, two daughters in law with infants, a fifteen year old who wants nothing to do with any of it, an uncle who arrives four days late, and a nurse. Each of those is a different day, and none of them can be planned from a summary.

We also ask who decides. In some families the itinerary is agreed by the matriarch and everything else is detail; in others the daughters plan and the parents are guests in their own holiday. Both work perfectly well and they produce completely different documents. What does not work is planning for a household through a single intermediary who is guessing at what the women of the family actually want to do with a Tuesday. Where we can, we take that part of the brief directly, and the itinerary is visibly better for it.

Pacing: the slowest member sets the day

The governing rule of a multi generational week is that the whole party never moves at once except to dinner. If you build a day that requires a ninety year old and a nine year old to be in the same car at the same time twice, you will spend the week apologising to both. So we build days with a single anchor and everything else optional: one fixed point at seven in the evening, and until then the household disperses into groups that suit themselves. This sounds obvious and it is almost never how families arrive planning to travel.

Heat and humidity make the pacing question sharper than it is at home. Gulf families arriving in June are not troubled by temperature, but Thai humidity is a different load, and it tires elderly parents and small children faster than the numbers suggest. So mornings carry anything active, from seven until about eleven. The middle of the day belongs to the house, the pool, the nap and the majlis, whether that is a formal sitting room or simply the shaded end of a terrace. Activity resumes after four. This is also, conveniently, the shape of the day that keeps you off busy beaches and out of crowded malls.

Parallel programmes

The practical unit is three or four simultaneous programmes with separate cars and separate staff. On a typical Phuket morning in one of the villa estates: the grandparents stay at the house with the pool warm and a therapist coming at ten; the mothers and older daughters take a boat to a cove and are back by one; the teenage boys are at a Muay Thai session; the small children are with the nannies in the shallow pool and then at the resort's activity room. That is four programmes, three vehicles and one coordinator, and it costs less to run than a single excursion that drags everyone along unwillingly.

Making this work is a staffing question rather than a planning one. We put one coordinator with the family for the whole stay whose only job is the moving parts: cars called, drivers briefed, timings adjusted when a nap runs long, the boat told to wait. Without that person, the burden of running four programmes falls on whichever daughter is most organised, which is precisely the outcome the trip was meant to avoid. With her, the household simply says what it wants at breakfast and the day assembles itself.

The shared evening meal

Everything else is optional; dinner is not. For most of the families we work with, the whole point of a long summer in one house is that twenty people eat together every night, and the single most important booking of the entire trip is the kitchen that makes it possible. In a staffed villa this means a cook briefed properly, halal supply lines agreed before arrival, and a serving arrangement that suits the household, whether that is a long table, a floor majlis with the food laid out, or the men and women in separate rooms with the same dishes going to both.

The details that decide whether it works are small. Enough seating in one place, which a lot of luxury villas do not have because they are designed for eight. A table that can be moved outside when the evening is dry and inside when it is not, in a green season where that decision is made at five o'clock. Serving staff who understand the order of service in the household. Coffee and dates available continuously rather than at the end. Space for the children to leave the table and come back. And a kitchen with the capacity for twenty covers a night for a month, which is a genuine constraint and one of the main reasons we sometimes move a family from a beautiful villa to a slightly less beautiful one.

Grandparents' comfort

Elderly parents are usually the reason a family chooses one property over another, and their requirements are concrete. A bedroom on the entrance level with no steps between it and the car. A walk in shower with a grab rail rather than a bath. Air conditioning that can be set warm, because villa systems are often calibrated for people who want fifteen degrees. A chair with arms, which sounds absurd until you stay in a designer villa furnished entirely with low seating. Lighting at night on the route to the bathroom. Somewhere quiet to pray that is not the middle of the family's day.

The other half is medical continuity, and we treat it as routine rather than as an emergency plan. Medication brought in original packaging with the prescribing paperwork, a written list of what is taken and when, the nearest private hospital identified and its international department told the family is in town, and a doctor who will visit the villa rather than the family visiting an emergency room. Bumrungrad International, Bangkok Hospital and Samitivej all run international departments with Arabic language support, and the Phuket and Samui private hospitals coordinate with them. None of this is medical advice; it is simply knowing the address before anyone needs it. Our guide to travelling with elderly parents treats the whole subject at length.

Where the party should stay

The adjacent villa arrangement deserves a note of its own because it is the answer for most large Gulf parties and few families arrive knowing it exists. On the Phuket and Samui estates it is possible to take two or three neighbouring houses that share a boundary and a service team. Each household has its own front door, its own pool and its own bedrooms; the families eat together in the largest of the three. It solves privacy between the households, solves the seating problem, and solves the sightline problem discussed in our privacy guide, since the neighbours are your own relatives.

A week that actually works

• Arrival day: nothing planned. Cars to the house, rooms allocated, dinner at the villa, the coordinator introduced to everyone by name.
• Day two: house day. Pool, spa therapists to the villa, the food and supply routine established, the kitchen brief tested before it matters.
• Day three: first split morning. Boat for one group, the market with a guide for another, grandparents at home.
• Day four: one shared outing, short, chosen for the grandparents, back by noon.
• Day five: children's day. Water park or the resort activity programme, older girls at the spa or the salon, quiet house.
• Day six: Friday. Nothing scheduled before the afternoon; the men to the mosque if that is the household's pattern, a long lunch, an easy evening.
• Day seven: shopping in Bangkok if the trip includes the city, or a second boat day if it does not.

Repeat with variations for as many weeks as the family is staying. Long stays fail from over programming far more often than from boredom, and the families who take a house for a month and use it as a house are the ones who come back the following June.

Villa capacities, kitchen arrangements and step free access should be verified in writing with the villa manager before booking, and hospital arrangements confirmed directly with the international patient office of the hospital nearest your property.
