Introduction
Having loyal customers in intense competition is a key factor for the success of organizations, therefore, the plans and strategies of organizations move towards the factors influencing customer loyalty, and obtaining customer satisfaction is an effective step to achieve this important goal (Fallah & Hamidi, 2021). Customer satisfaction is achieved when customers have a memorable and enjoyable experience of receiving services and products (Agarwal, Ira. Gowda, 2020).
 With the intensification of competition, companies have realized that providing a memorable experience to customers is very important to survive and gain a competitive advantage (Roozen & Katidis, 2019). Obviously, companies should focus on creating positive experiences to win the minds of customers (Micu, 2019); therefore, creating memorable experiences is important to retain old customers and attract new ones (Chen & Wu, 2022). However, the important factor in the formation of a valuable customer experience, followed by customer satisfaction; which enables the realization of customer loyalty, is the quality of service. Service quality is the ability of a product to meet the desired goal with the minimum possible cost (Bui et al., 2022). In the hotel industry, service quality is inevitable in order for the hotel to be distinguished from their competitors and to satisfy customers (Feng et al., 2018). In the meantime, the increase in the age of people and the expansion of the circle of elderly people in the society have led managers and hotel owners to plan and pay attention to providing quality services according to the wishes of the elderly (Prentice et al., 2022). Because increasing the satisfaction and loyalty of people of different ages requires knowing more about the different demands and needs of customers during their experience in the hotel. The organization can create value from providing its services and products when the service and product are provided according to the opinion and taste of the customers, which shows the intelligence of the managers in paying comprehensive attention to the customers (Mansouri et al., 2022). Therefore, improving service quality has become an important tool in the hotel industry in order to achieve a competitive advantage and retain customers. Satisfied hotel customers are more likely to return than dissatisfied ones (Liu, 2023). Currently, most organizations have realized that customer satisfaction can lead to their long-term success; the tourism industry, especially hotels, is no exception to this rule (Kim & Han, 2023). The best hotels consider customer satisfaction as the most important competitive weapon to achieve profit (Dah et al., 2023). According to the above explanations, the main question in the current research is whether the quality of service to the elderly through a memorable experience and satisfaction among the elderly customers of 5-star hotels in Mashhad leads to the loyalty of the elderly or not.
Theoretical Literature
Rachman et al., (2023) in a research entitled "Evaluation of the effect of service quality and product quality on customer satisfaction with the store" reached these results that service quality has a positive and significant effect on customer satisfaction. Prentice et al., (2022) conducted a research entitled "Investigating the role of memorable experience and emotional intelligence in the loyalty of senior customers to hotels for the elderly". The findings showed that service quality has a significantly greater impact on customer satisfaction, memorable experience, and customer loyalty. In addition, memorable customer experiences mediate the relationship between service quality and organizational outcomes. kiani et al., (2022) conducted a study entitled "Investigation of aesthetic factors and service quality on the perceived value, loyalty and satisfaction of customers of swimming pools in Kermanshah province". The results showed that there is a positive and significant effect between service quality and customer loyalty and performance.

Test results are aligned with research findings of Saberian & Mirmiran (2021), Prentice et al., (2022), Bahari & Bahari (2021), Saberian & Mirmiran (2021), Agarwal & Gowda (2020), Boonlertvanich (2019), and Nyamekye et al., (2021).
The results and examination of the hypotheses of the research model determined that service quality has a direct and indirect effect on the loyalty and return of elderly customers to 5-star hotels in Mashhad, and it is an important factor in increasing customer loyalty and creating a platform of attractive experiences for returning customers. Production and service organizations consider the level of customer satisfaction, especially the elderly, as a criterion to measure the quality of their work, and this trend is still increasing. The importance of elderly customers in their satisfaction is something that goes back to the global competition. In order to create satisfaction among the elderly, in addition to removing the causes of dissatisfaction and existing complaints, organizations should provide high-quality and attractive products and services in order to provide the elderly with happiness and a memorable experience, and provide the basis for increasing customer satisfaction and loyalty. By inferring the results, it is suggested that hotels provide the necessary preparations to strengthen the sense of security and peace in their seniors through quality and unique services. Also, in accordance with the wishes of the elderly customers, they strive for entertaining programs and services and continuously establish peace and security in the hotel.
