Sir
Tourism like any other industry has to satisfy the customers for its success. And in tourism the customers are the tourists. In order to attract the customers the industry has to take care of certain basic things. The first of these is security. Tourists must feel themselves secure when they are visiting a place. They should have no fear of being cheated or robbed. Next comes the system of transport. It must be easy, comfortable and not too expensive. The place must also be clean and should have attractive surroundings.
