The dynamic development of the sharing economy is clearly seen in particular, in the area of tourism in large cities. There is, therefore, an increasingly urgent need to study its impact on the functioning of cities, especially when they implement a sustainable development policy. Therefore, the need to study its impact on cities’ performances is more and more urgent, particularly, when they implement a sustainable development policy. This study discussed the influence of a sharing economy in tourism on city sustainability from the perspective of the Agenda 2030 goals. The main objective of the paper was achieved, thanks to in-depth analysis of the content of secondary sources. Results of the analysis were subjected to the synthesis process, using the tabular method. In Agenda 2030, when diagnosing the importance of this issue, one of 17 goals, i.e., goal 11, and 10 tasks within it, were devoted to the sustainable development of cities. The results of this study showed that sharing economy in tourism has an impact on the implementation of seven of them, but the direction of the impact is diversified. The domination of positive sharing economy (SE) effects was observed in the following areas: providing access to safe, affordable, accessible and sustainable transport systems for all (Target 11.2) and upgrading slums (Target 11.1), while the negative effects were noticed particularly clearly in implementing Targets 11.6 (reducing the adverse per capita environmental impact of cities) and 11.7 (providing universal access to safe, inclusive and accessible, green and public spaces).

This article investigates the research online, purchase offline (ROPO) behaviour patterns of holiday packages buyers during the planning and buying process and identifies the socio-economic factors (gender, age, education, number of people, including minors, in a household, place of residence or financial status, etc.) determining its occurrence. The research purpose was achieved based on the research results covering the behaviour of the holiday packages buyers (N = 989). To analyse the factors determining the ROPO behaviour, the methods of multidimensional statistical analysis – classification and regression tree – were used and confirmed the existing correlation between age, educational level and residence of tourist services buyers and the occurrence of their ROPO behaviour. Interestingly, the conducted research did not show the correlation between economic factors and the occurrence of ROPO behaviour of holiday packages buyers.

In the situation of insufficient subsidies for the substantive activities of museums, primarily the ones funded by the local governments, as well as low attendance of visitors, not really interested in the traditional offer of such institutions, there is an urgent need to extend it with additional elements corresponding to the expectations of a contemporary client. The observation of the thriving museums in Poland and worldwide indicates that cultural events represent such an attractive component which expands the museum offer. The article presents an attempt of explaining the role of cultural events in developing a museum product based on the analysis of a specific case of the Municipal Museum Gerhart Hauptmann’s House in Jelenia Góra-Jagniątków.

(1) Background: Uber Technologies are currently changing the pattern of urban transport. Statista reports that in the period 2017–2019 alone, the average monthly number of active Uber users worldwide increased by 126.5%, and the average monthly number of Uber trips grew by 115%. The purpose of this article is to identify the most important motives encouraging both current and potential customers to use Uber “taxi” services. Particular attention was paid to the factor of perceiving these services as a more sustainable way of meeting transport needs. Uber creates its image specifically on the idea of sustainability. (2) Methods: The operationalization of the sustainability concept was based on three dimensions: ecological, social and economic. The CAWI (Computer-Assisted Web Interview) technique was used to collect the research data. The representative research sample covered 1003 Poles. A logistic regression model was used to analyze empirical data collected based on the survey. The data analysis used R program and the selected packages for this program. (3) Results: Among the most important motives, sustainability is the most frequently indicated. (4) Conclusions: The choices of Uber services are significantly influenced by the reasons related to two sustainability pillars—one social and one economic. The factors significantly influencing consumer decision-making processes related to the use of shared mobility services belong to the following groups of motives: sustainable development, knowledge of information and communication technologies (ICT), innovation, user convenience and savings. The findings from the study can become the basis for organizations and local authorities to undertake appropriate marketing activities to promote shared-mobility services (SMS) and support sustainable and environmentally friendly development.

Customer loyalty to a destination and accommodation services constitutes a frequent object of research; however, customer loyalty to travel agencies is rarely analyzed. The presented article is an attempt to fill in this research gap. Its purpose is to construct and verify the model covering the impact of the selected factors on the loyalty level of customers of travel agencies operating in Poland. The conceptualization of the loyalty model of travel agency customers (based on the European path-based EPSI model) proposed in the article was first used to illustrate the existing correlations in customer behavior to analyze and explain the development of the loyalty phenomenon vis-a-vis travel agency customers. The aforementioned assumptions—having applied the structural equation modelling (SEM)—were reflected in the development of the theoretical model of travel agencies customer loyalty, the empirical verification of which (N = 1151) allowed us to determine the impacts of selected factors (i.e., the perceived quality of the travel agency’s offers, its image and the satisfaction with its service buyers) on the loyalty level of travel agency customers. It has been shown that two major factors have positive impacts on the loyalty of travel agency customers: (i) the perceived quality of travel agency offers, and (ii) its image. Furthermore, the conducted analysis highlights the positive influence of the perceived value of travel agency offers on the loyalty of customers.
