An all-inclusive resort is a holiday resort that includes at a minimum lodging, three meals daily, soft drinks, most alcoholic drinks, gratuities, and possibly other services in the price. Many also offer sports and non-motorized watersports and other activities that are included in the price as well. They are often located in warmer regions of the world, particularly in Mexico and the Caribbean.

Though some Butlin's holiday camps in the U.K. had offered a similar concept in the 1930s, the modern all-inclusive resort has its origins in the 1950s with the foundation of the Club Med company by Belgian entrepreneur Gérard Blitz. Their very first resort was opened in Alcúdia, Majorca, Spain in 1950, where guests stayed in tents and basic straw huts along the beach.

The concept has evolved over the decades. All-inclusives in the 1980s and 1990s were generally heavily marketed towards singles, whereas nowadays they are more popular with couples and families.

Those geared toward families may have facilities like craft centers, game rooms, and water parks to keep children of all ages entertained. All-inclusive resorts geared towards couples are also very popular locations for weddings and honeymoons.
