This research aims to study the demographic factors influencing the likelihood of repeat visits to the Learning Center under the Nong Yai Royal Development Project, Bang Luk Subdistrict, Mueang Chumphon District, Chumphon Province. The study examines key demographic variables, including age, gender, education level, occupation, income, and place of residence, as well as tourism behavior, satisfaction levels, and attraction factors that may influence the decision to revisit. A quantitative research approach was employed, utilizing a structured questionnaire to measure decision-making levels. Data were collected from 200 tourists and analyzed descriptively. The findings indicate that the majority of visitors to the Learning Center were female (56.0%), aged between 36 and 40 years (20.0%), self-employed (56.0%), with a bachelor’s degree (84.0%), and an average monthly income of 15,001 – 20,000 THB (28.0%). Most respondents were residents of Chumphon Province (44.5%). In terms of tourism behavior, most visitors were first-time visitors (25.5%), preferred staying at their own homes (36.0%), traveled by private car (62.5%), and usually traveled in groups of 3–4 people (46.5%), mostly with friends (56.0%). Their average expenditure ranged between 500–1,000 THB (29.0%). The most visited site in Chumphon was the Prince of Chumphon Shrine (26.0%), and within the project area, the Learning Center was the most favored attraction (32.5%). A high percentage (75.5%) of respondents expressed their intention to revisit. The study also analyzed decision-making factors influencing repeat visits, including attraction factors, location, accessibility, communication, perception, and barriers or concerns. The results revealed that attraction factors, location, accessibility, communication, and perception were rated at the highest levels, whereas concerns and barriers were rated at the lowest levels. Gender, location, and accessibility significantly influenced the likelihood of repeat visits, with female visitors showing a higher tendency to revisit compared to males. Key influencing factors included safety, convenience, and ease of travel. However, place of residence was found to have no statistically significant impact on the likelihood of repeat visits.
