Overview
Hotel Riviera del Pacífico was a resort hotel and casino in Ensenada, Baja California, Mexico. It emerged from the cross-border tourism boom associated with United States Prohibition, when American visitors traveled south of the border for entertainment, alcohol, gambling, and leisure. Ensenada developed as a destination after Tijuana and Rosarito, and local investors organized to build a large resort capable of attracting international visitors. The project began with the Ensenada Beach Club, S.A. After that organization dissolved in 1926, several of its members formed Club Internationale, S.A. to continue development. The proposed property was initially known as the Hotel Playa de Ensenada, or Ensenada Beach Hotel. Architect Gordon F. Mayer was hired to design the building, while Mexican artist Alfredo Ramos Martínez was commissioned to create murals. The resulting Playa Ensenada Hotel and Casino opened on October 31, 1930, with a major celebration that included the Xavier Cugat band. Boxer Jack Dempsey was associated with the hotel's early management. Although the hotel was promoted as one of Mexico's most prestigious and luxurious resort properties, its commercial performance was weak for much of its early history. Access from the United States depended on roads that were difficult by contemporary standards, and the repeal of Prohibition removed an important part of the cross-border demand on which the resort economy had been built. The property operated intermittently and was used for military purposes during the Second World War. The hotel experienced a postwar revival under Marjorie King Plant, who became associated with the property through Jerome Utley, one of its original shareholders and eventually its only remaining shareholder. Plant operated the hotel with her Mexican lawyer and husband, Alfonso Rocha, and renamed it Hotel Riviera del Pacífico. Under their management, the property reportedly achieved greater operational success than it had before the war. The arrangement later became entangled in legal disputes after Utley challenged the circumstances surrounding Plant's marriage and her control of the hotel. Plant left for the United States, while Rocha reportedly departed in 1956 to avoid a judgment. The Mexican government subsequently took control of the property. The hotel closed and was partly demolished in 1964, ending its life as a commercial resort. In 1978, portions of the site were rebuilt and reopened as the Centro Social, Cívico y Cultural de Ensenada. The surviving complex has included an open-air theater, a historical museum, a cantina, and rooms used for community and civic functions. The building is also associated with one of several competing origin stories for the Margarita cocktail. One account places the drink's creation at the hotel for Marjorie King Plant, although other accounts attribute it to Carlos Daniel “Danny” Herrera and locate the invention elsewhere.
History
The history of Hotel Riviera del Pacífico is closely linked to the development of tourism in Baja California during the United States Prohibition era. As restrictions on alcohol and associated entertainment encouraged American visitors to travel south of the border, destinations including Tijuana, Rosarito, and Ensenada sought to build facilities capable of serving an international clientele. The Ensenada Beach Club, S.A. was formed to develop a resort in Ensenada. When that organization dissolved in 1926, several participants created Club Internationale, S.A. and continued the project under the working name Hotel Playa de Ensenada. Architect Gordon F. Mayer designed the hotel, and artist Alfredo Ramos Martínez was engaged to produce murals. The property opened on October 31, 1930, as the Playa Ensenada Hotel and Casino. Its opening was staged as a major social event, featuring the Xavier Cugat band and an association with boxer Jack Dempsey, who acted as the property's de facto manager during its early period. The resort was intended to rank among Mexico's most luxurious hotels and to combine accommodation, dining, entertainment, and casino activity. The initial business model proved difficult to sustain. The road connection with the United States was poor, limiting access for the American visitors on whom the resort depended. The end of Prohibition further weakened demand for the hotel's entertainment and alcohol-centered tourism proposition. The property operated only intermittently and was placed into military service during the Second World War. The resort's fortunes improved after the war. Jerome Utley, an original shareholder who had become the remaining shareholder, transferred the hotel to Marjorie King Plant. Plant operated it with her Mexican lawyer and husband, Alfonso Rocha, and changed its name to Hotel Riviera del Pacífico. This period is remembered as the hotel's most successful operating phase. It is also the period associated with claims that the Margarita was created at the hotel for Plant, although the cocktail's origin remains disputed and other accounts credit bartender Carlos Daniel “Danny” Herrera at another location. The ownership and management arrangement later deteriorated into litigation. Utley had understood Plant's marriage to Rocha to be a marriage of convenience intended to provide Plant with the Mexican citizenship needed to operate the hotel. After discovering that the marriage was genuine, he pursued legal action against Plant and Rocha. The disputes contributed to Plant's departure for the United States and Rocha's departure from the hotel in 1956 while attempting to avoid a judgment. The Mexican government then took over the property. The government closed the hotel and partly demolished it in 1964. Fourteen years later, portions of the complex were rebuilt and reopened as the Centro Social, Cívico y Cultural de Ensenada. The adapted site has served as a cultural and civic venue, with facilities including an open-air theater, historical museum, cantina, and multipurpose rooms. The commercial hotel brand is defunct, but the surviving structure remains part of Ensenada's architectural and tourism history.
