Literally, the term resort refers to a place which a large number of people visit to spend their holidays, etc. For eg. Shimla. But in the hospitality industry, the term is used for referring to better facilities (usually for with-family stay) than what a hotel usually provides its customers. The duration of stay in a hotel is often very short, while that in a villa termed as a resort is could be longer. It is found that most of the enterprises which use the term 'resorts' in their names, provide independent villas/houses for such family-stay.

Hotel:

A hotel is an establishment that provides paid lodging, usually on a short-term basis. The provision of basic accommodation, in times past, consisting only of a room with a bed, a cupboard, a small table and a washstand has largely been replaced by rooms with modern facilities, including en-suite bathrooms and air conditioning or climate control. Additional common features found in hotel rooms are a telephone, an alarm clock, a television, and Internet connectivity; snack foods and drinks may be supplied in a mini-bar, and facilities for making hot drinks. Larger hotels may provide a number of additional guest facilities such as a restaurant, a swimming pool or childcare, and have conference and social function services.
