Las Vegas visitation plunged 58.6% in March; occupancy hit 39.8% Richard N. Velotta, Las Vegas Review-Journal · April 30, 2020 at 11:59 pm Visitation to Las Vegas plunged 58.6 percent to 1.5 million people in March and hotel occupancy was off 51.7 percentage points to 39.8 percent as the coronavirus took its toll on the state’s biggest industry. The Las Vegas Convention and Visitors Authority reported Thursday that convention attendance fell 54.8 percent to 249,800. March normally is one of the city’s strongest months for conventions and trade shows. Visitation numbers were dramatically affected by Gov. Steve Sisolak’s executive order March 17 directing the closure of nonessential businesses, including casinos and most hotels, to minimize the spread of the COVID-19 virus ravaging the United States.
