The Wet 'n Wild water park opened in 1985 and was located on the south side of the Sahara hotel. It closed at the end of the 2004 season and was later demolished. The opening of The Mirage in 1989 set a new level to the Las Vegas experience, as smaller hotels and casinos made way for the larger mega-resorts. The Rio and the Excalibur opened in 1990. These huge facilities offer entertainment and dining options, as well as gambling and lodging. This change affected the smaller, well-known and now historic hotels and casinos, like the Dunes, the Sands, and the Stardust.
