who built the rio hotel in las vegas
Rio All Suite Hotel and Casino The Rio opened on January 15, 1990, as a locals casino; it had been constructed and owned and operated by Marnell Corrao Associates. The opening acts were the Brazilian Group Sérgio Mendes '99 and Henrietta Alves of New Orleans, bringing the first two-piano act to Las Vegas, with various co-performers. A 20-story expansion tower was added to the current Ipanema Tower in 1993. Masquerade Village, a hotel tower and casino expansion including the Masquerade Show in the Sky, opened in 1997, at a cost of over $200 million. The Rio was purchased by Harrah's Entertainment in 1999 for $888 million. After the purchase, the Culinary Workers Union organized the Rio employees through card check recognition by enforcing the neutrality clause of the existing Harrah's contract on the new acquisition.[2]
