This dissertation examines how late-night events at museums can encourage repeat visits. It explores how the unique experiences offered at these evening programs, such as their informal social atmosphere, can create memorable moments for visitors and positively change their perception of the museum. Through case studies of late-night events at the Science Museum and Brunel Museum, the dissertation demonstrates how institutions of different sizes can successfully organize late-night events to fulfill educational goals and attract return visitors. The research aims to contribute to the limited existing literature on late-night museum programs by analyzing their potential benefits in helping institutions achieve broader objectives around audience engagement and repeat visitation.
