Rehab was a pool party event held from 2004 to 2018, at the Hard Rock Hotel and Casino in Paradise, Nevada, near the Las Vegas Strip.

Rehab popularized the pool party concept in Las Vegas, leading other resorts to begin offering their own versions.

Rehab also featured live performances throughout its history, from musicians such as Akon,[2] Snoop Dogg,[3][4] Drake, Lil Wayne,[5] Lady Gaga, Deadmau5,[6] Pauly D,[7][8] and Psy.

[15] Pallas had seen Nikki Beach in Miami, but he was not certain that such an idea could work in Las Vegas, so adjustments were made to the concept to suit the locale.

[18][19] Rehab was initially popular among local residents, including those who worked in nearby resorts on the Las Vegas Strip.

Word about the Rehab parties gradually spread to tourists, and the event pioneered the local trend of daylife (or dayclub) entertainment, similar to nightlife.

[26][27] The arrests prompted the Nevada Gaming Control Board to investigate aspects of the pool operation, to determine whether such crimes were commonly occurring on the property.

The lawsuit alleged that the resort was being portrayed on television as "a destination that revels in drunken debauchery, acts of vandalism, sexual harassment, violence, criminality and a host of other behavior".

[31] Describing the success of Rehab, Kohoutek said, "People want to come out and get some sun by the pool no matter what, but making it a nightclub atmosphere just entices them more.

Aside from pool renovations and expansions, the event stayed largely the same over the years, a fact that the Hard Rock Hotel cited as a reason for Rehab's success.

[38] In June 2018, it was announced that Rehab would come to an end later that year, as new owners prepared to renovate the Hard Rock and rebrand it as Virgin Hotels Las Vegas.
