Through systematically collecting, analyzing, and disseminating guest feedback information about their ever changing needs and wants as well as about any service failures that occur, the guest feedback system can be a very useful tool for hotel management. The data collected can be utilized by hotels to enhance quality, locate quality problems, and develop improvement procedures. This study attempts to explore guests' evaluations of guest feedback channels in China's hotels. Data were collected from 248 hotel guests at six hotels in China. Results reveal that the guest comment card is the most commonly used feedback channel by hotel guests and guest contact staff is perceived to be the most effective among all feedback channels. The results could have important implications for China's hotels when they try to develop successful guest feedback systems for their respective hotels.
