Casinos can also act as centers of attraction for tourists, thanks to which related businesses, such as hotels, restaurants, the sector of various services, air transportation, and so on, make a profit.
We can clearly see this from the profit statistics of such gambling centers as Macau and Las Vegas. Initially, only casinos were created there, which began to attract millions of tourists a year, which gave a huge boost to the development of related businesses.
The casino owners think smart to grow their place and integrate with the other business. We can see that the first time, the owner only open a casino, but as soon as they get a bigger profit, they buy bigger places and move the casino there. They also open the hotels inside the casino and use the hotel as the primary business, while the casino is just for the business's supports. Soon, the other casino is trying to do the same as them, and that is the way for the casino to grow their income and get more tourists to come.
