The term "American Plan" is often used in the hospitality industry to refer to a meal plan that includes three meals a day. However, there are several other terms that are used to describe this type of meal plan. One common synonym is "full board," which includes all meals provided by the hotel or resort. Another popular synonym is "all-inclusive," which typically includes not only meals but also drinks and certain activities. "Modified American Plan" is another option, which typically includes breakfast and dinner, but not lunch. Ultimately, it's important for travelers to understand the specific meal plan being offered by their chosen accommodations to ensure that they're getting the experience they desire.
