<![CDATA[TikTok is increasingly used by prospective travelers to search for tourism information, yet how perceived usefulness translates into continued platform use in premium tourism planning remains unclear. This study examines the relationships of perceived ease of use, attitude, and perceived usefulness with continuance intention to use TikTok for premium tourism information, with user satisfaction as a mediating variable within an extended Technology Acceptance Model. A cross-sectional online survey was conducted in Indonesia using purposive sampling, yielding 313 active TikTok users who had searched for premium tourism content and expressed interest in premium accommodation. Data were analyzed using partial least squares structural equation modeling with SmartPLS 4 and 5,000 bootstrap subsamples. The results show that perceived ease of use and attitude positively influence continuance intention, whereas perceived usefulness has no significant direct effect. However, perceived usefulness strongly increases user satisfaction, which in turn strongly predicts continuance intention. The indirect effect of perceived usefulness on continuance intention through user satisfaction is significant, indicating indirect-only mediation. The model explains 74.0% of the variance in continuance intention. These findings extend the Technology Acceptance Model by demonstrating that, in premium tourism information seeking, perceived usefulness supports continued TikTok use primarily by enhancing satisfaction rather than through a direct behavioral pathway. The results suggest that tourism marketers and content creators should prioritize useful, credible, and satisfying premium tourism content to sustain platform engagement. The findings are limited to continuance intention and should not be interpreted as evidence of purchase, destination visit, or actual tourism behavior.]]>
