Booking a holiday cottage for ten or twelve people is not the same as booking one for two. Most of the things that make a small cottage charming — a single bathroom, a galley kitchen, parking for two — turn into the things that ruin a large group holiday. After fifteen years of running Hole Mill as a 12+ guest property, here is what we have learned about what really matters when a group of ten or twelve is booking somewhere together.

This guide is biased — we run a large group holiday cottage in Devon, and it is one of the best ones, and we will say so. But the practical advice below is the same advice we would give a friend who was looking somewhere else.

1. Bedrooms vs. beds — count both

The single most common mistake guests make when booking large-group accommodation is reading "sleeps 12" without checking how those twelve people are actually distributed. Five double bedrooms is very different from three bedrooms and a sofa bed in the lounge. If half your group is going to end up in the kitchen at midnight, you do not have a 12-person property — you have a 6-person property with extra mattresses.

What to ask:

  • How many actual bedrooms are there?
  • How many are doubles, how many are twins, how many are bunks?
  • Where is the second living space? (You need somewhere to escape the main lounge.)
  • How many bathrooms? (See next section.)

For reference, Hole Mill is five ensuite bedrooms across two floors, with two further sleeping spaces (a snug with a double sofa bed, and a fold-out in the studio). Twelve people fit comfortably without anyone sleeping in a corridor or losing access to a real bathroom.

2. The bathroom rule

Our rule of thumb is one bathroom for every three guests. Below that, you will spend the first hour of every day waiting your turn for a shower. The mathematics of a single bathroom for ten people in the morning before a beach day is genuinely depressing.

Look for ensuites where possible. Even a half-bathroom (loo and basin only) saves arguments. If you are looking at a 12-person property with three bathrooms, you can probably make it work. With two, you cannot.

3. The kitchen

The kitchen does more work in a group holiday than any other room. Your group will eat at least one meal a day in it, more if the weather is bad. So:

  • Look for a real range or a double oven. A single domestic oven cannot cook a roast for twelve.
  • Two ovens are worth more than two of anything else. You can serve a starter and have a main going simultaneously without choreography.
  • Check the dishwasher. A 60 cm dishwasher running twice a day is far better than two sinks of washing up.
  • Look at the dining table. Twelve people need to actually fit around it, with elbow room. Two tables jammed together is a clue you should look elsewhere.

Hole Mill has an Aga, a separate electric oven, and a 14-seat oak refectory table that came out of an old Devon farmhouse. We have never had a group complain about the kitchen.

4. Outdoor space and a real reason to be outside

A group of twelve will not stay inside all day, even in November. The single thing that turns a good large-group cottage into a great one is what you actually do outdoors. Fire pit. Hot tub. Pizza oven. Pool. Sauna. Tennis. Big enough garden to play frisbee. None of that is decorative — it is what stops the group from getting cabin fever after twenty-four hours.

Hole Mill has two private acres. Wood-fired hot tub on the back lawn. Organic swimming pond with a diving jetty. A pizza oven we light on Saturday nights. A meadow you can play games on. The hot tub alone has saved more group holidays than we can count.

5. Parking, the boring critical thing

Twelve people probably means three or four cars. Some properties have a single drive that fits two — the rest park on the road and walk. In Devon, "the road" is often a single-track lane, and parking on it is a problem for the locals and for you. Always ask explicitly:

  • How many cars can park on-site?
  • Where do extra cars go?
  • Is there a turning point or do you have to reverse a quarter-mile?

Hole Mill has off-road parking for six cars and a turning area for any others. EV charger included.

6. Privacy and noise

A large group makes noise. That is not bad — it is one of the points. But you do not want to spend the weekend worrying about the neighbours. The best large-group properties are either fully detached with no close neighbours, or in genuinely rural locations where sound disperses.

Hole Mill sits in a private valley. Our nearest house is half a kilometre away through woods. You can put music on the lawn at midnight and no one will hear it.

7. Heating, hot water and Wi-Fi

People underestimate how much hot water twelve guests use. Every shower, every washing-up cycle, every evening of dishes. Look for properties with proper unvented hot-water cylinders sized for the number of guests, or with an instant electric supplement. Ask the host directly: "If everyone showers in the morning, will the last person get a cold one?"

Same with heating: Devon stone houses can be cold in shoulder seasons. A wood-burner is lovely but it is not central heating. Ask if the property is fully heated.

And Wi-Fi: at least two people in your group will need to do some work or upload photos in the evening. Hole Mill has Starlink. Even in our valley with no mobile signal, the Wi-Fi is faster than most London flats.

8. Linen, towels and "what you bring"

Some properties expect you to bring everything. For a couple in a one-bed cottage, fine. For a group of twelve, hauling sheets and towels for everyone is genuinely ridiculous. Insist on linen and towels included, plus pool / hot tub towels if relevant. Ask whether they provide tea, coffee, oil, salt, pepper, washing-up liquid, dishwasher tablets and bin bags. The answer should be yes for all of them.

9. The host

Read the reviews carefully. The single biggest predictor of a good large-group stay is whether the host responds within an hour when something goes wrong. Twelve people generate problems faster than two — somebody locks themselves out of the studio, the dishwasher trips, somebody's phone needs the Wi-Fi password resent at midnight. You want a host who treats this as part of the job, not as an interruption.

10. Cancellation policy and the deposit

Big group bookings are expensive. Read the cancellation policy carefully. Look for a deposit you can recover if a couple of people drop out (within reason). Look for a clear refund window. Avoid anywhere that is rigid about either.

We are obviously biased, but: Hole Mill in Branscombe is purpose-set up for groups of 10–12, with five ensuite bedrooms, four bathrooms, a big kitchen, a hot tub, a swimming pond and Starlink. Most of our weekends are large group bookings — friend reunions, family Christmases, milestone birthdays, hen parties. If that is what you are planning, check our availability and have a look at the property tour. If somewhere else is a better fit for you, the checklist above is what to ask them.
