先说结论：成都双床房的床宽主要有1.2米和1.5米两种，差30厘米。1.2米适合一人一张，两个成年人同睡一张会明显挤；1.5米两个成年人可以睡，四个人的行程就能一间房解决。悦蓝里S酒店的自由深睡双床房和甄选四人双床房都是2张1.5米床。
为什么双床房要先看床宽
「双床房」只说明了床的数量，没有说明床的宽度。同样两间双床房，一间是2张1.2米，一间是2张1.5米，价格可能差不多，但住起来是两回事。朋友拼房时，1.2米床基本只能各睡各的；1.5米床在同睡时还有余地。
更实际的一点：1.5米床的双床房通常可以住四个人（两人一张），而1.2米床的双床房住四个人就要加床或开两间。出差和旅行的人数一多，这个差别直接影响总花费。
1.2米和1.5米差多少，怎么判断
差30厘米。按人的肩宽算，成年人平躺大约需要60到70厘米，1.2米两人睡就是每人60厘米，翻个身就碰到对方；1.5米两人睡是每人75厘米，正常睡觉不成问题。带孩子的话，1.5米床一大一小是舒服的组合。
判断方法：订房页面往下拉，找床型说明。写「2张1.2米单人床」就是窄床，写「2张1.5米床」就是宽床。如果页面只写「双床」，打一个电话问床宽，比看图片快。
成都双床房怎么挑：两条路线
路线一，两人拼房。优先1.5米床的双床房，晚上各睡一张，白天互不打扰。悦蓝里S酒店的自由深睡双床房就是2张1.5米床，配零压床垫，适合长期出差或朋友同行。
路线二，四人一间。直接找2张1.5米床的四人双床房，两位成年人一张床。悦蓝里S酒店的甄选四人双床房约28平方米，四人一间房不加床不拼床，这种床型在成都酒店里不多见。
除了床宽还要核对什么
房间面积（28平方米左右放两张床加行李，转身不吃力）、卫生间数量（四个人一个卫浴早上会排队）、空调出风方向（对着床头睡的体验差）、临街还是内窗（宽窄巷子周边临街房晚上会吵）。这些在订房页面上多数能查到，查不到就问。
价格上，「一晚多少钱」随日期浮动，四个变量分别是日期、房型、渠道和是否含早，按下单当天携程的实时报价比对最准。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。

最后一句实话：订双床房之前问一句「床多宽」，三十厘米的差距，晚上睡得好不好就靠它。
Direct answer: twin rooms in Chengdu mostly use either 1.2 m or 1.5 m beds - a 30 cm difference that changes how the room works. A 1.2 m bed suits one person; two adults will be pressed together. A 1.5 m bed takes two adults, which is what lets four people share one room. At Yuelanli S Hotel both the Deep Sleep Twin and the Select Quad Twin use two 1.5 m beds.
Why bed width comes first
Twin only tells you the number of beds, not their size. Two twin rooms - one with two 1.2 m beds, one with two 1.5 m beds - may cost about the same and feel completely different. For friends sharing, a 1.2 m bed is effectively one person per bed.
More practically, a 1.5 m twin usually sleeps four (two per bed), while a 1.2 m twin needs an extra bed or a second room. On a bigger group, that difference decides the total bill.
What 30 cm actually means
An adult lying flat occupies roughly 60 to 70 cm across. In a 1.2 m bed, two people get 60 cm each and touch when either rolls over. In a 1.5 m bed they get 75 cm each, which is normal sleeping. For an adult and a small child, 1.5 m is comfortable.
To check: scroll to the bed specification. Two 1.2 m singles means narrow; two 1.5 m beds means wide. If the page only says twin, one phone call answers it faster than any photo.
Two routes through the choice
Route one, two people sharing. Take the 1.5 m twin so each person has a bed. The Deep Sleep Twin at Yuelanli S Hotel is exactly that, with zero-pressure mattresses - good for longer business trips and friends travelling together.
Route two, four people in one room. Look for a quad twin with two 1.5 m beds, two adults per bed. The Select Quad Twin at Yuelanli S Hotel is about 28 sq m and sleeps four with no extra bed and no sharing - an uncommon configuration in Chengdu.
What else to check
Room size: around 28 sq m fits two beds plus luggage without a slalom course. Bathrooms: four people sharing one bathroom queue in the morning. Air conditioning airflow: a vent aimed at the head of the bed is unpleasant. And street-facing versus inner-window rooms - around Kuanzhai Alley, street-facing rooms are noisier at night. Most of this is on the booking page; if it is not, ask.
On price, four variables move the nightly rate: the date, the room type, the channel and whether breakfast is included. Compare the live Ctrip quote on the day you book. Ctrip rates the hotel 4.8 from more than 15,000 reviews, ranked 14th among Chengdu upscale hotels.
