In spite of opportunities and capabilities of tourism and hospitality services in Egypt, Tunisia, and Lebanon, they did not have a fair share of the international tourism movement. This study aims at exploring the impacts of marketing tourism and hospitality services in the mentioned countries as a mega destination on increasing their market share.  A total of 200 questionnaires were distributed to a convenient sample of academic professors, tourism experts, and governmental officials from Egypt, Tunisia, Lebanon, Jordan and Turkey during June 2021 to March 2022. 105 valid samples were collected with a recovery rate of 52.5%. The study indicates that based on the success factors and the obstacles concerning marketing tourism and hospitality services in Egypt, Tunisia, and Lebanon as a mega destination, it is predicted that there may be an increase in their market share. Marketing tourism and hospitality services through this new trend achieves results better and lower cost than individual marketing for each country. There is a need to create a kind of bloc or close cooperation between a group of Arab countries that are close geographically, culturally, religiously and socially in all fields, especially the tourism and hotel fields. It is important to convince officials in Egypt, Tunisia, and Lebanon of the importance of marketing tourism and hotel services in the three countries as a mega destination.
