In 1974, the Guinness Book of World Records named Circus Circus as the world's largest permanent circus, a distinction that it continues to hold. Pink coloring is used throughout the resort. Jo Harris was the original interior designer. She had previously designed Caesars Palace, and would later work with Sarno on other projects. The 1972 hotel tower gave the casino 409 rooms. Another 15-story tower was opened in April 1975, adding an additional 400 rooms, and a convention hall. The two original towers are connected, and are known as the Casino Tower. In the 1970s, the hotel included a two-story Royal Suite, which was designed by Harris and included a balcony. A wedding chapel, known as Chapel of the Fountain, also opened in 1975. The Circus Circus carousel was removed in 1976, to make room for the resort's new roadside sign, which stands 123 feet. The neon sign depicts a clown character known as Lucky.

Circus Circus Manor, which opened in 1980, consists of five, three-story motel buildings with a total of 810 rooms. This brought the resort's overall total to 1,610 hotel rooms.
