The aim of the article is to assess the legal nature of the form of restricting access to activities in the field of organizing tourist events (as well as facilitating the purchase of linked travel services), which was introduced by the Act of 24 November 2017 on package travel and related travel services. The form of regulation of access to the above-mentioned activity does not, in essence, differ from that provided for in the provisions of the Entrepreneurs' Law Act in the case of regulated activity. However, it is not one of the three forms of regulation of economic activity known to the Law of Entrepreneurs, although it also includes the pursuit of economic activity. Therefore, it follows from the above that the catalog of forms of regulation of economic activity regulated by this Act is in some sense incomplete. The use of the regulated activity model by the legislator for the purposes of the system of restricting access to activities in the field of organizing tourist events and facilitating the purchase of related tourist services resulted in duplicating not only the advantages but also the disadvantages of the model.
