Nightclub is drinking, bouncing, singing K, rows of stalls collectively, right, I personally do not think it is not considered to refer specifically to a particular project, you can say to go to the nightclub to drink, you can also say to go to the nightclub bouncing.

Sleeping places called hotels, that is because in addition to providing accommodation services, hotels can also provide food and beverage and banquets, cocktail parties and other projects, but also the hotel is different from the general hotel place.

The other way around, the place to drink is called a hotel is also right actually, but the place to sleep no one called a nightclub.
