Wellness tourism represents a powerful intersection of two large and growing sectors, the $2.6 trillion tourism and $4.5 billion wellness sectors. Holistic health and prevention are increasingly at the center of consumer decision-making, and people now expect to continue their healthy lifestyle styles and wellness routines when they are far from home. The offer of wellness tourism services is of increasing importance for tourists who use them, because the very specification of this service includes relaxation, peace, health treatments aimed at regenerating physical health and eliminating stress. In this context, the quality of this service should be highly standardized and its offer should include services of a specific character that will fully meet the expectations of tourists. With the application of appropriate standards of such quality, wellness tourism services can reach a high level of quality and user satisfaction. The quality of the wellness service in tourism is very important because tourists expect to get the maximum effect for the price they pay. In wellness tourism, there are certain certificates and quality standards that measure the degree of quality, and they include certificates of wellness experts, ISO certificates held by wellness centers, the WellBuilding certificate, but also reviews of tourists and users of wellness services, which they leave on tourist portals, and which they can be a guide to others in their quest for wellness. Since this is a specialized type of service that is aimed at optimizing the relaxation of the user's mind and body, wellness experts strive to put maximum effort into the wellness offer and its implementation, in order to achieve the maximum effect for the user.
