Despite increasing investments in mobile technologies by organizations in tourism and hospitality, challenges persist in effectively enhancing customer experiences. To address this, innovative promotional strategies are focusing on engagement through gaming and gamification, which are among the most popular trends. This research aims to expand on existing gamification studies by exploring a fun ecosystem within hotel gamified mobile applications, examining the relationships between different user types. A study involving 495 hotel visitors with mobile app experience found that interactions within such a gamified ecosystem can significantly enhance the fun for users. The proposed model suggests that the element of fun can be further amplified when combined with other enjoyable elements.
