Guest check-in is the process where visitors arrive at a hotel, resort, or other accommodation and officially register their stay. During check-in, guests typically provide identification, confirm their reservation, and receive room keys or access cards. This process ensures that the establishment has accurate records of who is staying and helps manage room availability. The check-in process may vary depending on the establishment. Some places offer self-service kiosks for quicker access, while others have staff available to assist guests. Additionally, many hotels now provide online check-in options, allowing guests to complete the process before arriving, enhancing convenience and efficiency.
