One evening in November, a cousin calls: “What if we all spent Christmas together this year? With my parents, my brothers, their kids… how many would we be? Twenty? Twenty-three?”
It is a lovely idea. The logistics, much less so. Bringing twenty people together for a week is a small project in itself: lodging, travel, meals, space, privacy, activities. Everything has to be thought through. And everything can go wrong if you type “chalet for 20 people Alps” into Booking without asking the right questions first.
We host tribes this size at Arpian. Family reunions spanning four generations, 50th birthdays, teams of sports coaches on their annual retreat, corporate retreats. We have seen what works, and what does not. This article is our method — the one we would give a friend doing this for the first time.
Why 20 people changes everything
With 6 people, you rent a large apartment and nobody complains. With 12, you rent a nice chalet and the stay works. From 15-16 people on, everything changes. The logistics are not the same, expectations are different, and an undersized chalet becomes unlivable within 48 hours.
Here is what happens past that threshold:
- The bathroom becomes the bottleneck. With 6, you work it out. With 20, it is war — unless you have 10 bathrooms.
- The kitchen becomes mission-critical. Cooking for 20 is not just “cooking for 6 × 3”. You need double the counter space, two ovens, two fridges, a commercial dishwasher.
- The shared spaces have to handle everything happening at once. While 8 kids are playing, the parents want to read in peace, and 4 teenagers want to watch a movie. Without several zones, there is friction.
- Subgroups need room to breathe. 20 people do not do everything at the same time. Each family, each little clan has its own rhythm — and the chalet has to allow for it.
“For the week, the chalet is really a small village. And like any village, it has to be designed so nobody steps on anyone else’s toes.”
The 8 mistakes that ruin a stay for 20
Mistake #1 — Underestimating the number of bathrooms
This is mistake #1, by far. Many chalets advertise “sleeps 20” with 4 or 5 bathrooms. A 1:5 ratio is unworkable. For 20 people, you need at least 8 bathrooms — ideally 10. Any fewer and you will spend the week waiting your turn for the shower. Especially when everyone comes back from the slopes (4pm-7pm).
Mistake #2 — Confusing beds with bedrooms
A chalet that “sleeps 20” can mean 8 bedrooms + 4 beds in the mezzanine, or 10 bedrooms with 2 beds each. The difference is huge. Sleeping in a bedroom means having a space of your own, where you can put your things away, talk quietly, rest during the day. Sleeping in a mezzanine means sharing everyone else’s noise and light. For a family reunion or a corporate retreat, insist on closed bedrooms.
Mistake #3 — Forgetting about the “kitchen” zone
A stay for 20 easily means 5-6 meals a day to coordinate: staggered breakfasts, lunch for the non-skiers, an afternoon snack for the kids, aperitifs, dinner. A standard chalet kitchen is too small for that. Check for: two ovens, two cooktops, a commercial dishwasher, a fridge of at least 500 liters, and a large counter.
Mistake #4 — Overlooking spaces for the kids
In a group of 20, there are often 6 to 10 children. If you do not have a dedicated space for them (game room, home cinema, table football, arcade machine), they take over the living room. And a living room for 20 with no kids’ zone means constant noise.
Mistake #5 — Choosing a chalet with no après-ski
A ski trip for 20 is not just about skiing. It is also (and above all) the moment when everyone gets back together after the slopes. Without a wood-fired hot tub, a sauna, a big living room with a fireplace, a cocktail bar — the stay becomes a simple string of days. With these spaces, it becomes a stay to remember.
Mistake #6 — Underestimating linens and cleaning
20 people × 7 days is 140 nights. That means 20 sets of sheets, 20 sets of bath towels, 20 bathrobes, 20 pairs of slippers, 6 full loads of laundry. If the chalet does not provide everything (bedding, linens, bathrobes, final cleaning), you will spend half the stay doing laundry. Or worse: having to bring it all yourself.
Mistake #7 — Not thinking about parking
20 people easily means 4 to 6 cars. Many chalets in ski resorts have only one or two private spaces. Check: how many spaces in front of the house, how many free public parking lots nearby, and whether there are seasonal parking rules that will force you to move the car every night.
Mistake #8 — Booking without talking to the host
Booking a chalet for 20 people on Booking without having spoken to the owner is like buying a house from a catalog. A stay for 20 deserves a conversation. A good host will ask you questions: how many children, allergies, expectations, ski level, meals. And will plan ahead. That is what makes the difference between a rental and real hospitality.
At Chalet Arpian, we welcome up to 23 people.
10 bedrooms, 10 bathrooms, an adjacent apartment that sleeps 8 more. The capacity of a small hotel, the intimacy of a family home.
Discover Arpian →Getting the size right: real capacity vs listed capacity
On rental platforms, “maximum capacity” is misleading. A chalet “for 20 people” may have a comfortable capacity of 14, and 20 only fit if you squeeze 6 people into the mezzanine and 4 into the living room. Listed capacity ≠ comfortable capacity.
To assess real capacity, ask yourself these questions:
- How many closed bedrooms, with a door, and a double or twin bed?
- How many bathrooms? Ideally, you want a ratio of 1 bathroom for 2-3 people at most.
- Is the shared space (living room + dining room) at least 860 sq ft? Any smaller, with 20 people, and it feels stifling.
- How many toilets separate from the bathrooms? Crucial for the morning rush.
- Is there a private area for the hosts/managers? If they sleep in the chalet with you, that is a red flag.
| Criterion | Chalet undersized for 20 | Properly sized chalet |
|---|---|---|
| Living area | 2,150-3,230 sq ft (cramped) | 4,300 sq ft or more |
| Closed bedrooms | 6-7 bedrooms | 10 bedrooms |
| Bathrooms | 4-5 shared bathrooms | 8-10 private bathrooms |
| Shared space | 540 sq ft living room | Living room + kids’ zone + dining room |
| Parking | 2 spaces + make do | 3-4 private spaces + public parking |
The golden rule: 1 bathroom for 2 people
If you remember only one thing from this article, make it this: the ratio of bathrooms to guests is the number one success factor for a stay with 20 people.
Why? Because on a ski trip, everyone comes back from the slopes between 4:30pm and 5:30pm. Everyone wants to shower right away. Everyone wants to be ready for aperitifs at 7:30pm. That is 60-90 minutes to get 20 people through the shower.
With 4 bathrooms (a 1:5 ratio), you need to allow 15 minutes per person and set up a schedule. With 10 bathrooms (a 1:2 ratio), everyone goes whenever they like. The difference in experience is radical.
We chose to have 1 bathroom per bedroom. That means 10 bathrooms for 15 beds in the main chalet, and 1 more bathroom in the adjacent apartment. It is one of the best ratios in the resort.
The 3 essential zones of a chalet for a tribe
A chalet for 20 people cannot work with a single large room, however huge. You need at least three distinct zones that can be lived in at the same time.
Zone 1 — The main living room (the heart)
Fireplace, big sofas, natural light, a view. This is where you have aperitifs before dinner, meet up over an après-ski coffee, read a book while others chat. This zone has to be large, bright, and calm.
Zone 2 — The dining room (the ritual)
A big table for 20 is the central ritual of the stay. Never underestimate the importance of a table where everyone fits. It is the moment when the tribe counts itself, sees itself, talks. A chalet where you have to eat in two sittings or split across two tables is a chalet that misses the point.
Zone 3 — The game room or Family Room (decompression)
This is the “if you want to make noise, go over there” zone. Arcade machine, table football, home cinema, games table. For the kids, it is their kingdom. For the adults, it is the place to unwind once the little ones are asleep. Without this zone, all the noise piles up in the living room — and evenings become exhausting.
“Three zones that can be lived in at the same time: that is the secret. That is what turns a chalet into a small village.”
A former discotheque turned game room.
In Arpian’s basement, we kept the soul of the hotel’s former discotheque: arcade machine, table football, home cinema, stone bar. 485 sq ft devoted to unwinding, away from the main living room.
See the Family Room →What it really costs, and how it splits
A high-end chalet for 20 people in the Alps generally costs between €8,000 and €35,000-40,000 a week depending on the resort, the time of year and the standard. That may sound like a lot, but per person it is often better value than the same experience in individual rentals.
The math per person
Take a chalet at €12,000 a week for 20 people:
- Cost per person: €600 for 7 nights = €86/night
- Compared with a 4-star hotel in Valmorel: €180-220/night for a double room
- Compared with Valmorel's 5★ residences, for 23 people for the week of 13 to 20 February 2027: from €21,304 at Akoya (4 apartments for 6), tourist tax included (rate observed on 27 October 2026) — 4 kitchens, no evenings together. Arpian, same week: €12,577, chalet and apartment, tourist tax included.
A private chalet is almost always the best value for money beyond 10 people. And that is before counting the experience: everyone under one roof, shared common spaces, the spirit of a stay that builds day by day.
How the bill splits
Here is a typical per-person breakdown for a one-week ski trip for 20:
| Item | Per person / week | Tribe total (×20) |
|---|---|---|
| Lodging | €500-700 | €10,000-14,000 |
| 6-day adult ski pass | €290-340 | €5,800-6,800 |
| Equipment rental | €110-180 | €2,200-3,600 |
| Restaurants & groceries | €200-350 | €4,000-7,000 |
| Total / person | €1,100-1,570 | €22,000-31,400 |
On top of this total come the extras that are often essential with 20 people: a private chef for 1-2 dinners (from €35 per person, drinks not included), in-chalet massages, activities other than skiing. But also real savings: booking direct with no commission (10 to 22% saved depending on the platform).
For a chalet at €10,000-15,000 a week, negotiate directly with the host rather than going through the platforms. You will save the commission (often 10 to 22%), have a single point of contact, and be able to tailor the services.
What Arpian offers tribes of 15 to 23
We built Arpian around one obsession: letting a tribe of 15 to 23 people come together without compromise. Here is what that means in practice.
Flexible capacity: 15 or 23
The main chalet sleeps up to 15 people in 10 bedrooms with 10 private bathrooms. For larger tribes, an adjacent apartment that sleeps 8 can be added — 20 m away, with no break in the experience. You can book the chalet alone, or the whole property.
10 bedrooms = 10 bathrooms
Every bedroom has its own bathroom. No line in the morning, no shower schedule after the slopes. It is one of the best ratios in Valmorel, and it was our non-negotiable principle during the renovation.
Three distinct zones for living side by side
The large living room (1,075 sq ft of shared living space), the dining room (a table for 20+), and the Family Room in the basement (485 sq ft, a former discotheque). Three zones that let several subgroups coexist without friction.
The wood-fired hot tub ritual
On the terrace, an XXL wood-fired hot tub. We light it at 5pm, we get in at 7pm. In between, we talk. It is slow, it is beautiful, it is our signature.
The hotel-style service experience
Beds made on arrival, bathrobes and slippers, linens included, final cleaning, firewood for the hot tub provided, fiber Wi-Fi, private parking. The comfort of a hotel, the intimacy of a chalet.
Booking direct
We always offer the best rate direct, with no platform commission. That is 10 to 22% less than on Booking, Airbnb or Greengo, for the same stay.
Your tribe is expected.
One tribe at a time. A personal welcome. A stay with no compromise on hotel comfort or the intimacy of a chalet.
See our availability →Frequently asked questions
What is the recommended minimum group size for renting a chalet for 20 people?
A chalet for 20 people usually breaks even at around 10-12 guests. Below that, the cost per person is higher than with smaller rentals. Above it, it is very good value: a chalet for 20 costs about the same as several apartments in a high-end residence for 15 people, and far less for 23 — with everyone under one roof. For Christmas 2026, for 15 people: from €10,600 in a 5★ residence (2 apartments), from €11,000 for Arpian. In February 2027, for 23 people: from €21,304 in a 5★ residence (4 apartments), €12,577 for Arpian, chalet and apartment, tourist tax included.
What kinds of stays work in a chalet for 20 people?
Family reunion (3-4 families with children), vacation with friends (15-25 people), a milestone birthday (30th, 40th, 50th), a corporate retreat (8-20 colleagues), a sports retreat (groups of coaches and athletes), or simply a big family vacation.
How many bathrooms do you need for 20 people in a chalet?
The rule is 1 bathroom for 2 people at most. A chalet properly sized for 20 people should have at least 8-10 bathrooms. At Chalet Arpian, we have 11 bathrooms for 23 beds (10 in the chalet, 1 in the apartment), a ratio of 1:2.1 — one of the best on the market.
How do you avoid group conflicts on a stay with 20 people?
Three principles: (1) each subgroup needs its own private space (bedroom + bathroom), (2) the shared spaces must let several subgroups do their own thing at the same time (a reading corner while others play), (3) a shared program that is optional, not mandatory (one meal together each day, the rest à la carte).
Which resorts are best for a stay with 20 people?
The resorts best suited to it are human-scale village resorts (Valmorel, La Clusaz, Les Saisies, La Tania). The most upscale resorts (Méribel, Courchevel, Val d'Isère) have few chalets this size, often at prohibitive prices. Mid-size resorts (Les Arcs, La Plagne, Tignes) offer choice, but often in more impersonal residences.
How far in advance should you book a chalet for 20 people?
For school vacations (Christmas, February), allow 9 to 12 months in advance. Outside school vacations, 4 to 6 months is enough. Chalets of this capacity are rare — there are usually fewer than 5 per resort. So plan ahead as soon as the group has made its decision.
