The $1.9 billion Palazzo casino-resort, developed by Las Vegas Sands Corp., is set to celebrate its grand opening from Thursday to Saturday.
It includes a concert featuring Motown superstar Diana Ross.
By the grand opening, roughly 2,300 of the 3,068 rooms are expected to be available, while 50 percent of the shopping mall's tenants will be in business.
It is the first new property on the Las Vegas Strip since the April 2005 opening of Wynn Las Vegas.
