A guest book is a book or digital platform where visitors can leave their names, messages, and sometimes comments about their experience. Commonly found in places like hotels, wedding venues, and museums, guest books serve as a way for hosts to remember their guests and gather feedback. These books can also be used for special occasions, such as birthdays or anniversaries, allowing friends and family to share their thoughts and well-wishes. Guest books often become cherished keepsakes, preserving memories and sentiments for years to come.
