In Philadelphia, the park closures have shuttered the City Tavern.

On Cape Cod, the Nauset Knoll Motor Lodge is closed.

But not all private companies on park land have been shut down. Two high-profile places in San Francisco, the Argonaut Hotel in San Francisco Maritime National Park and Cavallo Point, a luxury hotel in Golden Gate National Park, are open.

The Park Service says those are operating under lease agreements rather than as concessions, which means they are allowed to stay open.

“Concessions operations are required to close; leases are permitted to remain open,” Mike Litterst, a spokesman for the parks, said in an email to The Washington Times.
