LAS VEGAS (AP) — One of the biggest casino projects on the Las Vegas Strip has announced a June 24 opening date. Resorts World Las Vegas said Monday it will debut more than 3,500 rooms at its three Hilton-branded hotels. The $4.3 billion development by Malaysia-based Genting Group has been under construction since May 2015, but experienced delays and redesigns. The project will open during a pandemic that has upended the Las Vegas economy with business restrictions intended to slow the spread of COVID-19. Nevada Gov. Steve Sisolak has set a June 1 goal for 100% reopening of businesses after March 2020 closures.
