What term describes an arrangement where the room rate includes a light or continental breakfast?

The term that accurately describes an arrangement where the room rate includes a light or continental breakfast is known as the "Continental plan." This plan typically features a range of lighter breakfast options, such as pastries, bread, fruit, and beverages, rather than a full meal.

Other terms presented, such as "Breakfast Inclusion Plan," do not correspond to widely recognized industry terminology and do not specify the kind of meal included. "Modified Full Board" usually indicates that some meals are included, but it typically refers to a plan that includes breakfast, lunch, and dinner, potentially with some meals excluded. The "Half Board Plan" includes breakfast and one additional meal, typically dinner, rather than just breakfast on its own. Thus, the term "Continental plan" succinctly captures the essence of a package that provides a basic breakfast with the accommodation rate.
