Does Cooking for 20 Really Save Money?

1. Work out which half of the bill you are actually comparing

Search for how much you save cooking for yourself in a rented villa and you get two kinds of answer: cooking for yourself costs half of takeaway, or a head of food costs about thirty yuan. Neither is wrong, but both only count half the bill - they count ingredients. Ingredients are barely a quarter of what a meal actually costs.

Start with the ingredient bill, using the official listed retail prices from the Deqing County Bureau of Commerce consumer price monitoring table dated 15 October 2026:

• Meat and fish 126.75 yuan: 4 kg boneless leg pork at 48.00, 2 kg dressed chicken at 22.00, 1.5 kg grass carp at 16.50, 2.5 kg eggs at 16.25, 8 blocks of tofu at 24.00.
• Vegetables, staples and seasonings 83.05 yuan: 3 kg cabbage at 6.00, 1.5 kg leafy greens at 6.75, 2 kg tomatoes at 9.00, 5 kg rice at 16.50, 0.3 barrel of rapeseed oil at 21.90, salt 6.40, soy sauce 8.00, sugar 8.50.
• Drinks 54.00 yuan: one case of pure milk, 24 boxes.

2. Three hidden costs turn that headline saving into something much smaller

Before you bank the difference, three costs have to come off it, and not one of them appears anywhere in the listing data:

After those three, the real gap on one dinner falls from 736 yuan to around 550, about 27 yuan per person. That is the honest answer to how much self-cooking saves. Count only the ingredients and you overstate it several times over; add the opportunity cost of two people spending three hours at the sink and the saving can turn negative.

One more volume that is easy to miss: can the ingredients for twenty actually fit in the fridge. The word fridge appears in only 29 room names across the whole site, mostly small in-room units, and the size of any kitchen fridge is not recorded anywhere in the listing data.

• Gas: bottled LPG is 145 yuan per 14 kg cylinder in the official table, plus 15 yuan delivery within 8 km. Three cooked dinners need three cylinders, 480 yuan with delivery, 24 yuan a head.
• The trip into town: of the 42 properties with a kitchen, the median straight-line distance to Wukang county town, where the nearest full-size market and supermarket are, is 11.2 km, and only 12 are within 10 km. That is thirty kilometres of mountain road each way, and the shopping for twenty people will not fit in one boot, so two trips is the realistic plan.
• Labour: one cooked dinner for twenty needs about two hours of washing and cutting plus one hour of clearing up, with at least two people on it. That is three hours of somebody’s time.

3. What actually limits you is not the kitchen, it is the market

Most people assume the precondition for cooking is a kitchen. Kitchen coverage here is genuinely thin: 42 of the 100 properties have one, and of the 19 that sleep 30 or more only 4 do. But the binding constraint is the second gate, whether you can buy the food.

Stack the three conditions of sleeping 20 or more, having a kitchen, and sitting within 10 km straight of Wukang town, and only 6 properties in the whole set survive. The 20 to 29 band is tighter still: 17 of 42 have a kitchen, and only 5 of those are within 10 km of town.

In other words, for a villa that sleeps 20 and where you intend to cook, Moganshan is not a choice of 42, it is a choice of 6. That is the thing to settle before you book, rather than booking first and working out the shopping later.

4. The best kitchens are also the furthest from the market

There is a counter-intuitive layer on top. Of the 42 properties with a kitchen, 36 list it as a shared kitchen, and only 6 are flagged as separate: Yucun Xiaozhu Moganshan Garden Town (sleeps 30), Moganshan Yugang Suxi Huatian (16), Lingshang Mingshu (24), Chic Jiuye (12), Yinxi 39 (18) and Zhuxi Pan Molishan Ju (16).

Only 2 of those 6 sleep 20: Yucun Xiaozhu sits 10.6 km from Wukang town, Lingshang Mingshu 12.3 km. Of all 6, only one lies within 10 km of town, and it sleeps 12. The combination you actually want, twenty people plus a private kitchen plus a market round the corner, does not exist in this set.

This is structural rather than accidental: the larger houses sit on the scenic-area side and further from the town centre, while the smaller ones in town happen to be closer. If you pick the self-cooking route you have to accept that trade: either further out, or smaller.

5. When self-cooking is genuinely worth it: three conditions together

Pulling the previous sections together, self-cooking pays off only when all three of these hold at once. Miss any one and the case largely falls apart:

One more thing often mistaken for a saving, which is not: 46 properties offer food delivery, and 23 of them also have a kitchen. The same houses can do either. The difference is money and labour, not whether dinner is possible. Once you see that, you know which of the two you are actually buying.

• First, a group that is not too large and where someone volunteers. Twenty is already on the large side; in the 10 to 19 band, 21 of the 39 have a kitchen, the widest choice. What decides the outcome is whether somebody is willing to put in those three hours, not how many yuan the ingredients save.
• Second, a house close to town, or a willingness to make an extra trip. The 12 kitchen properties within 10 km can be supplied in one run; of the 19 beyond 12 km, either shop a day ahead and confirm the fridge will take it, or pay double in driving.
• Third, cooking one meal rather than three. The money is in the cooked dinners, but so is the labour. What is actually worth it is breakfast and a late supper: same ingredients, and you dodge the most valuable continuous block of time after 14:00.

6. Three cases where the saving is an illusion

In these three situations the money you appear to save is not real:

• Groups of 30 or more. Only 4 of the 19 have a kitchen: just 1 of the 7 that sleep 30 to 39, and 3 of the 12 that sleep 40 or more, most of them shared. At that scale shopping and washing become an engineering project, and a set team meal is easier to control.
• One night only, and you want one good dinner. 99 properties hand over rooms at 14:00 or later and 98 ask you to leave by 12:00, so the most continuous stretch of the 22 hours you have is the afternoon into the evening. Trading that for chopping vegetables in order to save ten yuan a head has the priorities backwards.
• Nobody in the group wants to cook. This is the most common case. The saving only counts if it comes out of the group’s budget; if in the end the boss and two colleagues are the ones washing up for two hours, the direction of the calculation changes.

7. What to do, by headcount

Turning the accounting above into a decision you can act on:

• 10 to 19 people: the realistic band for self-cooking. 21 of the 39 have a kitchen and the share close to town is highest here. One cooked dinner plus breakfast works well. The cash saving is modest, but the atmosphere of cooking together cannot be bought.
• 20 to 29 people: 17 of the 42 have a kitchen, and only 5 of those are within 10 km of town. Plan a single night with dinner and breakfast cooked, leave the main meal to a set team menu, and spend the difference on better dishes and one more activity.
• 30 people and up: drop self-cooking. 4 of 19 have a kitchen and most are shared. If you want to save money, save it on a better team meal.
• With children or elderly members: only 30 properties mention children’s meals at all, and 13 of those are among the 58 with no kitchen. For a group with kids the time cost of cooking rises sharply.

8. Five questions to get answered on the phone

None of these answers exist in the listing data. You have to call, and you have to ask for figures rather than impressions:

• Is the kitchen ours alone for the group, or shared with other guests? 36 of the 42 are listed as shared.
• How many burners, and are there large pots and woks? Across every room name and facility field in the data, pots, burners and ovens never appear once.
• How big is the fridge, and can it hold three days of food for twenty? The word fridge appears in only 29 room names, mostly small in-room units.
• Do you provide gas or firewood, or do we buy it ourselves, and at what price per cylinder? The official price is 145 yuan per cylinder plus 15 yuan delivery.
• If twenty of us drive to town to shop for one meal, how long does it take from your gate to the market, and can the supermarket deliver? 82 properties list a taxi service, but a taxi round trip to town means handing two hours over to the car.
