Health & Safety

In May, MGM Resorts released its comprehensive “Seven-Point Safety Plan,” a multi-layered set of protocols and procedures designed in conjunction with medical and scientific experts to mitigate the spread of the virus, protect customers and employees and rapidly respond to potential new cases. As time passes, the company will continue to evaluate and evolve its safety protocols. Key initiatives from the MGM Resorts plan as well as specific to MGM National Harbor include:

·Employee screening, temperature checks and COVID-19 specific training

·Employees and guests will be required to wear masks in public areas. Masks will be provided free of charge

·Guest temperature checks at casino floor entrances and hotel front desk

·A physical distancing policy will be implemented, with floor guides serving as reminders

·For areas where physical distancing presents challenges, plexiglass barriers will be installed, or other measures will be used to reduce risks

·Standalone handwashing stations designed by MGM Resorts conveniently located on the casino floor

·Contactless Check-In through the MGM Resorts App will allow hotel guests to go through the check-in process on their personal devices, minimizing interactions

·Guestroom Attendants will wear masks and gloves while cleaning each room and will change gloves between guestrooms

·In addition to increased and enhanced routine cleaning of guestrooms and public spaces based on CDC guidance, electrostatic sprayers will be utilized in many large public spaces so that disinfectant is applied efficiently

·Digital menus will be available to view on personal mobile devices via QR codes in the resort’s food and beverage outlets

·To minimize groups congregating while they wait, restaurant guests will receive text message notification when their tables are ready

·MGM has compiled its own internal team and processes to respond if a guest or employee tests positive for COVID-19. We ask that if a guest tests positive after visiting one of our properties, they alert us through a special email address (covid19@mgmresorts.com). We will immediately report any positive test results to the local health department and assist with contact tracing to support the health department investigators.

Per the Governor’s guidelines, the property will adhere to a 50% capacity limit.
