The original casino, Union Plaza about the railroad station, included a small waiting room for Amtrak train passengers.

[4] The hotel was built on the station site by Upland Industries (Union Pacific's real estate division), along with the Scott Corp, headed by Frank E.

[8] Before the discontinuation of the Desert Wind train route on May 10, 1997, Amtrak built its Las Vegas station directly connected to the hotel.

During his ownership, D.W. Barrick's friend, Larry Manetti, who played Orville "Rick" Wright on the television show Magnum, P.I., hosted a celebrity brunch every Sunday, featuring such guests as Pat Morita and Steve Rossi.

In 2014, the Plaza announced that a new 3,500-seat facility would be constructed at the hotel to become the new home arena for the Las Vegas Wranglers minor league hockey team of the ECHL.

[17] In 2016, the Plaza fully refurbished its rooftop pool, creating an outdoor space with a wet deck, hot tub, private cabanas, bar, and food truck.

[18] The Plaza built the multipurpose venue CORE Arena, an equestrian center in downtown Las Vegas with 80 equine stalls,[19] which hosts events like rodeos and monster truck shows.

[26] The Main Street renovations also included Pinkbox Doughnuts across from Carousel Bar and a smoke-free gaming area that opened in partnership with Brian Christopher on the other side.

Overlooking the new Main Street venues is a rooftop patio at Oscar's Steakhouse, an al fresco fine dining space.
