These are typical words in the hotel industry, with a few minor variations in the case of an All Inclusive package.
Bed & Breakfast is a combination of lodging and a morning meal (Breakfast).
Lodging + Dinner + Breakfast is considered half board.
The order of meals that constitutes full board is your choice: lunch, dinner, and breakfast.
All-inclusive packages include lodging, three meals, and drinks. As a promotional offer, some hotels include local alcoholic beverage choices +/- an evening or morning snack in this bundle.
