Generative AI—especially ChatGPT—has shown great promise in tourism, particularly as an itinerary planner. A recent study compared three-day itineraries created by ChatGPT for Vienna, Plovdiv, and Spetses against those designed by tourism While ChatGPT excelled in crafting clear and accessible plans that are ideal for initial travel inspiration, it often fell short in accuracy and specificity when weighed against expert-curated itineraries. Across 11 quality criteria, findings showed that ChatGPT-based itineraries consistently included only permanent attractions such as museums and landmarks, frequently neglecting critical logistical elements like time schedules, transport routes, meal suggestions, and local insights . Another drawback stems from the AI’s static dataset cutoff; although ChatGPT may appear up-to-date, it can present outdated or incomplete information (e.g., closed attractions or changed schedules), which can mislead non-expert travelers
