Proceedings of 10th Asian Business Research Conference 6 - 7 October 2014, Novotel Bangkok on Siam Square, Bangkok, Thailand, ISBN: 978-1-922069-62-7 The Factors Affecting the Satisfaction of Tourists Who Use Thai Spa Services Area of Bangkok Arunothai Juntavong The objectives of this study are: 1) to explore the factors that affect the satisfaction of tourists using Thai Spas, and 2) to better understand the requirements that might improve ‘Thai Spa’ business management, in order to improve efficiency and effectiveness, and 3) to determine how to develop Thai spa businesses. In the research methodology section of the paper, the adoption of empirical research methodology (Mark Easterby-Smith, 2008)is explained and described, in order to gather information regarding the factors affecting the satisfaction of tourists who use Thai spa services. Furthermore, the choice of the data collection procedure and qualitative data analysis are also justified. The research findings were as follows: The people who provide spa services to tourists can be considered a factor affecting service satisfaction. The ‘therapist’ is a person who is directly involved in providing services and who directly affects tourists, because the therapist provides a most essential service. Tourists expect to receive a very good service, but the service provided can have both good and bad consequences. The service itself can satisfy customers, but the key factor affecting tourists the most is the people themselves. It is therefore necessary to focus upon the work of such personnel, in order to deliver a good service performance and to provide a guide for conducting effective business in the future.
