Wynn Resorts, MGM Resorts, the Venetian, and the Cosmopolitan are among the first in the Las Vegas to drop the mask requirement for fully vaccinated customers. Guests who are not vaccinated are still required to wear a mask.

Wynn Resorts operates the Wynn Las Vegas and adjacent Encore on the east side of the Las Vegas Strip, where the Desert Inn stood for decades.

MGM Resorts owns several major hotel casinos in Las Vegas. Many are on the west side of the Strip, including the Mandalay Bay, Bellagio, and Mirage. The company also owns the MGM Grand on the east side of the resort corridor.

Wynn Resorts employees are required to wear a mask unless they can provide vaccine verification. MGM Resorts employees are required to wear face mask.

The Cosmopolitan is not requiring masks for fully vaccinated guests and employees. The resort towers over the older Jockey Club on the west side of the Strip.

The Venetian and adjacent Palazzo are on the east side of the Strip at the site of the now demolished Sands Casino. Fully vaccinated patrons are not required to wear masks but employees are required to.

Nevada Gaming Control Board said it is up to each operator whether to check that a customer has been vaccinated. In a statement, Wynn Resorts said it trusts guests “to take the appropriate precautions based on their personal vaccination status.”

The issue of how to confirm whether a casino customer has been vaccinated became a topic of debate on social media in these days.
