网络百科辞典维基百科关于room service 有如下解释:
Room service or "in-room dining" is a hotel service enabling guests to choose menu items for delivery to their hotel room for consumption there. Room Service is organized as a subdivision within the Food & Beverage Department of high-end hotel and resort properties (http://en.wikipedia.org/wiki/Room_service)。
从上文不难看出,所谓的room service 就是指高级宾馆为客人提供的送餐服务。
为了进一步验证room service 是否就是指宾馆的“送餐服务”,笔者尝试通过Google搜索到了美国的一些旅馆内部关于room service的说明。
美国波士顿的Seaport Hotel & World Trade Center 在其网页上对其提供的餐饮服务有如下介绍和宣传:

芝加哥的Drake Hotel in Chicago 对于其提供的In-room dining 服务介绍如下: A full course meal, refreshment, a choice selection from the wine list, and appetizers just right and light, or how about breakfast in bed? Room Service at the Drake Hotel is available Sunday through Thursday, 6 am to 1 am and Friday through Saturday, 6 am to 2 am.

亚特兰大的Atlanta Four Seasons Hotel 在向客人介绍其餐饮服务时候有着如下文字:Four Seasons Hotel Atlanta In-Room Dining is a fine-dining experience within the comfort and convenience of your guest room or suite. Choose from an extensive room service menu – day or night – that is ideal for time-zone-hopping travelers and impromptu meetings, or for quiet, private dining.
该旅馆对其餐饮服务的时间说明如下:

那么,宾馆的客房服务,应该怎么说呢?http://www.wisegeek.com/what-is-a-hotel-housekeeper.htm#slideshow 网站对什么是housekeeper做出了详细的解释: A hotel housekeeper is an employee of a hotel who is responsible for keeping rooms and other areas of the establishment clean. A hotel housekeeper will typically be responsible for cleaning rooms in the hotel every day, with a particularly thorough cleaning after guests check out on their last day. On a day to day basis, cleaning rooms may involve making beds, swapping used towels for fresh ones, cleaning and disinfecting the bathroom and providing new toiletries as provided by the hotel, vacuuming the carpet, and taking the trash away. When a guest checks out, a hotel housekeeper will change the sheets on the bed and polish the furniture. In addition, the housekeeper will take any forgotten items to lost and found. While a hotel housekeeper is cleaning, he or she takes account of the room and notices whether or not everything is working properly. If a light bulb is burned out, for instance, she may be responsible for replacing it, or for calling maintenance to fix a light fixture. Hotel housekeepers may be responsible for keeping the rest of the hotel looking nice as well, by vacuuming the carpeting found in stairs, hallways, conference rooms, and the lobby, among other areas. It might also be necessary to clean the furniture or the windows.
从上文看出,housekeeper就是我们所知的宾馆的“客房服务员”,尤其是黑体下划线部分的解释十分清楚地表明了其职责范围。此外,“客房服务员”还可以表达为housekeeping attendant。有关网页介绍如下:Housekeeping attendants are responsible for keeping rooms and public areas at hotels, motels and other lodging establishments clean.
至此,我们也不难推断出,宾馆的“客房部”就是housekeeping department,而“客房服务”,则可以说housekeeping services,而room service绝不可以望文生义地理解为“客房服务”。
