In an extraordinary move, the National Park Service announced Thursday that it was changing the names of The Ahwahnee hotel, Curry Village and other beloved park sites. The move, officials say, was forced on them by an intellectual property dispute with the park’s departing concessions company.

“We feel we have to change the names,” Yosemite spokesman Scott Gediman said in an interview Thursday. “With the ongoing litigation, we feel this step is necessary.”

The famed Ahwahnee is slated to become The Majestic Yosemite Hotel. Curry Village will become Half Dome Village, and the Wawona Hotel will become Big Trees Lodge.
