Detail: In 1927, the Hampton Beach Casino was purchased by John J. Dineen, John Cuddy, and Napolean Demara and a new era in the Casino's history began. A little more than a quarter of a century after the Casino's founding, radio, records and motion pictures were creating a new kind of entertainer - the national star. The new owners quickly moved to design a "ballroom" large enough to accommodate 5,000 people.
Patterned on old English ballrooms, the new owners incorporated part of the old Opera House and added space toward the south end of the complex. The ballroom's wooden dance floor was one of the largest in the region and it soon became the most popular nightspot in the area. Each week, more than 20,000 people danced in the air-conditioned ballroom.
