The word hotel derives from the French hôtel (coming from "hôte" meaning "guest"), which referred to a French version of a townhouse or any other building seeing frequent visitors, not a place offering accommodation (in contemporary usage, hôtel has the meaning of "hotel", and hotel particullier is used for the old meaning). The French spelling (with the circumflex) was once also used in English, but is now rare. The circumflex replaces the 's' once preceding the 't' in the earlier hostel spelling, which over time received a new, but closely related meaning.
Basic accommodation of a room with only a bed, a cupboard, a small table and a washstand has largely been replaced by rooms with en-suite bathrooms and, more commonly in the United States than elsewhere, climate control. Other features found may be a telephone, an alarm clock, a TV, and broadband Internet connectivity. Food and drink may be supplied by a mini-bar (which often includes a small refrigerator) containing snacks and drinks (to be paid for on departure), and tea and coffee making facilities (cups, spoons, an electric kettle and sachets containing instant coffee, tea bags, sugar, and creamer or milk).
Some hotels offer various combinations of meals as part of a room and board arrangement. In the United Kingdom, a hotel is required by law to serve food and drinks to all comers within certain stated hours; to avoid this requirement it is not uncommon to come across "private hotels" which are not subject to this requirement. However, in Japan, capsule hotels offer minimal facilities and room space.
The cost and quality of hotels are usually indicative of the range and type of services available. Due to the enormous increase in tourism worldwide during the last decades of the 20th century, standards, especially those of smaller establishments, have improved considerably. For the sake of greater comparability, rating systems have been introduced, with the one to five stars classification being most common.
The star classification system is a common one for rating hotels. Higher star ratings indicate more luxury. The AAA and their affiliated bodies use diamonds instead of stars to express hotel and restaurant ratings levels. Hotels are independently assessed in traditional systems and rest heavily on the facilities provided. Some consider this disadvantageous to smaller hotels whose quality of accommodation could fall into one class but the lack of an item such as an elevator would prevent it from reaching a higher categorization.
In some countries, there is an official body with standard criteria for classifying hotels, but in many others there is none. There have been attempts at unifying the classification system so that it becomes an internationally recognized and reliable standard but large differences exist in the quality of the accommodation and the food within one category of hotel, sometimes even in the same country.
