This paper investigates the effect of perceived service modularity on the customer experience of visitors to theme parks. The study was conducted in collaboration with two of the largest theme parks in Europe, comprising quantitative data from 658 visitors in total. The findings shows that perceived service modularity positively affects the customer experience, and all the thereto associated dimensions (sense, feel, think, act and relate), as measured in this study. Complementing the dominating qualitative approaches in research on service modularity, this paper adds insights on the effects from modularity on the customer experience in the tourism industry.
