Alamo's son, Tony Alamo Jr, a former chairman of the Nevada Gaming Commission, confirmed that his father died on Tuesday after several years of illness.
A memorial service will be held on 18 October at Our Lady of Las Vegas Catholic Church, followed by burial at Palm Mortuary-Eastern.
Born in Isabela de Sagua, Cuba, in 1941, Alamo escaped the country during political upheaval, arriving in Miami in 1961 with only $7.
After working odd jobs, he relocated to Reno, Nevada, where he began employment at Harrah's Casino as a janitor before training as a dealer. By the 1970s, he had moved to Las Vegas with his family, starting a management career that would span three decades.
Alamo served as president of Circus Circus before moving to head the Desert Inn. His most notable role came with MGM Grand, where he became President and COO during its development into what was then the largest hotel in the world.
MGM Resorts, where Alamo once held senior roles, continues to expand its international digital strategy.
In August 2025, MGM and Playtech launched Family Feud live from the MGM Grand casino floor, part of a broader "Live from Vegas" initiative aimed at regulated markets worldwide.
Throughout his career, Alamo was recognised for his contributions to Nevada's hospitality industry. He was named Hotelier of the Year by the Nevada Hotel and Lodging Association in 2001 and in 2003, the state's Board of Regents awarded him the title of Distinguished Nevadan.
Later in life, Alamo battled Parkinson's disease and Lewy body dementia. He remained an advocate for education, with a Las Vegas elementary school named in his honour and several scholarships established at the University of Nevada, Las Vegas (UNLV).
Clark County School District Superintendent Jhone Ebert described him as "a passionate advocate of freedom, integrity and education," noting his long-standing support for public schools in Nevada.
Alamo later helped to develop the Monte Carlo, now Park MGM, before retiring in 2005 as SVP of Mandalay Resort Group
