Hilton and American Express are partnering on an initiative to provide up to one million hotel room nights for doctors, nurses, paramedics, and other frontline medical staff who need somewhere to sleep or safely self-isolate between April 13 and the end of May, the companies announced Monday. Rooms will either be paid for by Hilton and American Express or, in some cases, donated by individual hotel owners.

“During this crisis, we have seen so many examples of medical professionals working in the most challenging circumstances, sacrificing their own needs for the greater good,” Hilton President and CEO Christopher Nassetta said in a statement. “They truly are heroes.”

Hilton is initially working with 10 medical associations, including the American Hospital Association and the Society of Critical Care Medicine, to assist the organizations’ more than one million members find a place to sleep away from home as a precautionary measure against spreading coronavirus to family members.

Rooms will be available across a variety of Hilton brands and be staffed by team members who underwent additional safety and health training to protect themselves and guests during the ongoing pandemic. Hotel rooms and common areas will also be sanitized with industrial-grade cleaners and updated cleaning protocols in light of coronavirus.
