What term describes a holiday option where all meals, drinks, and activities are included for one price?

The term that best describes a holiday option where all meals, drinks, and activities are included for one price is "all-inclusive." This concept is popular in resort settings and vacation packages, where travelers pay a single upfront price that covers a wide range of services, eliminating the need for additional payments during their stay. This model provides convenience and allows guests to enjoy various amenities without worrying about extra costs. The appeal of all-inclusive holidays lies in their predictability and the ability to budget effectively, as everything is accounted for in the initial cost.

In contrast, other terms such as "full-service" may indicate a broad range of service offerings but do not specifically guarantee that all meals and activities are included. "Semi-inclusive" suggests that some but not all amenities are covered, leaving gaps in the coverage that guests would need to pay for. "Specialty vacation" refers to a themed or niche type of holiday rather than a pricing structure and doesn't convey the same all-encompassing nature as an all-inclusive package. Thus, "all-inclusive" is the most accurate term for this type of holiday experience.
