Star Trek: The Experience is a theme attraction at the Las Vegas Hilton in Las Vegas, Nevada, USA, based on the fictional Star Trek universe. To date the Experience has undergone one major renovation, re-opening 18 March 2004. The renovation added the "Borg Invasion 4-D" ride, which uses state-of-the-art technology to try to convince visitors that they are having an encounter with the Borg (Krutzler, 2004). Star Trek: The Experience is operated by entertainment management company Cedar Fair Entertainment Company after its June 2006 purchase of Paramount Parks from the CBS Corporation.[dead link] The attraction may close before the year is over.
