Smart hotels in China will use robots to carry luggage, install facial recognition for easier check-ins, and use smart keys on phones to turn on air conditioning, predicts Jane Sun, CEO of CTrip, one of China's largest online travel services company. And you won't even have to leave a tip. "I think this will happen because the labor cost available in the world will increase, and using machines to do something that is logical and programmable is a very feasible way to make sure a customer is satisfied and efficiency is improved," Sun told CNBC's Geoff Cutmore at the East Tech West conference held in the Nansha district of Guangzhou, China.

Sun said her company's focus is on new online visitors who are more interested in domestic travel than overseas because of the weak currency in China. "Almost 75 percent of our customers are younger than 35," said Sun, whose company has 300 million registered users. "Chinese people like to try new things ... and the idea in our young people's minds will be like a Star Wars hotel where you have little futuristic themes designed in it."

Innovative tracks and expansion

The travel services provider, which operates trip.com, is known to constantly innovate and drive sales by providing new offers to travelers. International expansion is one of its key objectives for next year. CTrip made two good investments in the U.K., said Sun, one of which was the Skyscanner booking platform which allows for travelers to do price comparisons on airlines and hotels during the booking process. Skyscanner saw revenue growth of about 250 percent in CTrip's last quarter. Its "low-star hotel" bookings surged to nearly 50 percent during the quarter.
