Step-by-step explanation:
When a travel agent arranges a vacation at Disney World that includes airfare, lodging, and dinner reservations for the Smith family, this industry is best known as the tourism industry. The tourism industry is a significant component of the service sector and plays a pivotal role in generating wealth and employment. It encompasses a broad range of services, including travel assistance, accommodation, and recreational activities.
