I think that IT system is important for F&B department because this department have to use IT system quite a lot such bill posting, billing, order food in the system to related with kitchen or called this system as POS: Point of sale which used to make bill payment when guests come to restaurant and use the service. For hotel, a lot of customers use online booking to reserve the room because they can booking by themselves easily, quickly, and conveniently. So, IT system is very useful for hospitality industry because it help staffs working with standard, fast and correctly. I think the social media maybe make hotel business successful and make more profit easily, if the hotel use it to promote and advertising because social media can invite many customers to join with us such as participate with special activities, know current hotel's information, review from customers etc.
