This paper examines the relationships between service quality and visitors’ satisfactions and behavioral intentions in theme parks. The items for measuring service quality are developed and expected to be practically useful for theme park management and to enhance the visitors’ satisfactions eventually. These items are grouped into seven meaningful dimensions: entrance area, rides, restaurants, shows, shops, park facilities, and park atmosphere. Results show that while park atmosphere has an important impact on visitors’ satisfactions, ride impacts significantly on revisit intentions and willingness to recommend to others. These findings suggests useful management implications for theme parks.
