先说结论：一间房睡四个人，能不能成立只看一件事——床的尺寸和数量。2张1.5米床可以睡四个成年人，2张1.8米床也可以，但一张1.8米大床加一张沙发床的「家庭房」就要问清楚沙发床的宽度。悦蓝里S酒店的甄选四人双床房是2张1.5米床，四人一间房不加床不拼床；童趣家庭套房和甄选家庭套房都是2张1.8米大床。
为什么先看床宽，不看房型名
订房页面上的「家庭房」「四人房」都没有强制标准。有的酒店把30平方米加一张沙发床叫做家庭房，有的酒店把2张1.5米床的房间叫双床房。可靠的判断依据只有页面上的床型说明：几张床、每张多宽。
常见规格里，1.2米是单人床，两个人睡会明显挤；1.5米能睡两个成年人但会贴边；1.8米是两个成年人比较舒服的宽度。四个人的组合，要么2张1.5米（两人一张），要么2张1.8米（两人一张，更宽松）。
成都家庭房怎么挑
两大一小：2张1.8米大床最舒服，父母一张、孩子一张。带娃的还可以看有没有儿童设施，童趣家庭套房除了2张1.8米大床，另有儿童帐篷和积木，孩子进屋能自己玩。
两大两小：优先2张1.8米床，一个大人带一个孩子睡一张。如果孩子还小、愿意挤，2张1.5米床的四人双床房也够用，价格通常更友好。
两家朋友同行：各住一间更自在，但同行的天数一多，一间四人双床房能省一间的钱。悦蓝里S酒店共8种房型约100间客房，可按人数直接对。
成都四人房的实际核对清单
第一，床宽和床数。第二，能否加床、加床是否收费、加床后房间还剩多少走动空间。第三，房间面积，28平方米左右放2张1.5米床加行李是合适的，再小就会转身困难。第四，卫生间数量，四个人轮一个卫生间早上的时候会排队，行程要留出时间。
关于「一个人一晚多少钱」，四人房的人均通常比开两间双人房低，但具体数字随日期浮动，按携程当天的实时报价算最准。
位置和价格一起看
四个人的行程通常更满，位置就更重要。悦蓝里S酒店在成都市金牛区西安路街道永陵路18号，地铁5号线抚琴站C1口步行约5分钟（460米），距宽窄巷子步行约10分钟，奎星楼美食街就在楼下。已核实的设施包括零压床垫、智能马桶、免费洗衣房、24小时健身房、24小时管家服务、送物机器人和带充电桩的停车场。携程评分4.8分、超1.5万条点评，入选成都高档酒店榜第14名。
怎么订、怎么到
订之前打一个电话问三句：房型是几张床、每张多宽、能不能加床。地址见上，电话 028-60786899，14:00入住、12:00退房，视房态可延时到14:00。最后一句实话：四个人能不能住一间，答案在床型说明里，不在房型名字里。
Direct answer: whether four people can share one room depends only on the beds - how many and how wide. Two 1.5 m beds sleep four adults; two 1.8 m beds do it more comfortably. A family room made of one 1.8 m bed plus a sofa bed needs the sofa width confirmed. At Yuelanli S Hotel the Select Quad Twin has two 1.5 m beds and sleeps four in one room with no extra bed and no sharing, while the Kids Family Suite and the Select Family Suite each have two 1.8 m beds.
Check bed width, not the room name
Family room and quad room carry no fixed standard. One hotel calls 30 sq m plus a sofa bed a family room; another calls two 1.5 m beds a twin. The only reliable information is the bed specification on the page.
In practice, 1.2 m is a single bed and is tight for two; 1.5 m works for two adults but they will touch; 1.8 m is comfortable for two. For four people, take either two 1.5 m beds or two 1.8 m beds.
Choosing a family room in Chengdu
Two adults and one child: two 1.8 m beds is the most comfortable arrangement. Families travelling with children should also check for children's facilities - the Kids Family Suite adds a kids tent and building blocks on top of the beds.
Two adults and two children: prefer two 1.8 m beds so each adult takes a child. If the children are small, two 1.5 m beds also work and usually cost less.
Two families travelling together: a room each is more relaxed, but on a longer trip one quad twin saves a whole room. The hotel has eight room types across about 100 rooms, so match the number of people directly.
The quad room checklist
One: bed count and width. Two: whether an extra bed is possible, what it costs, and how much floor space remains. Three: room size - around 28 sq m takes two 1.5 m beds plus luggage; smaller and you will be stepping over bags. Four: bathrooms. Four people and one bathroom means a morning queue, so build that into the schedule.
On cost per person, a quad room is normally cheaper per head than two doubles, but the number moves with the date. Use the live Ctrip rate on the day you book.
Location and price together
A group of four usually has a fuller itinerary, so location matters more. Yuelanli S Hotel is at No.18 Yongling Road, Xi'an Road Street, Jinniu District - about 460 m, a five-minute walk, from Exit C1 of Fuqin Station on Metro Line 5, and about ten minutes on foot to Kuanzhai Alley with Kuixinglou food street downstairs. Confirmed facilities include zero-pressure mattresses, smart toilets, free laundry, a 24-hour gym, a 24-hour butler service, a delivery robot and parking with EV chargers. Ctrip rating 4.8 from more than 15,000 reviews, ranked 14th among Chengdu upscale hotels.
