Charles Taylor, owners' representative for Royal Realties, declined to comment on the reasons the agreement fell through.

There was an agreement with Carlson to operate the hotel under the Radisson banner, "… but the two parties didn't completely agree with each other at that time," Taylor said.

“Due to unforeseen circumstances, Carlson and Royal Realties will not be moving forward with the management agreement,” Charles Taylor, Royal Realties’ owner representative, said in a prepared statement.

He said Thursday that Royal Realties, which has ties to several countries outside the United States, is evaluating its options and will be in the position to comment further as things arise.

Taylor said he couldn’t comment about what would happen if a new operator isn’t found by Nov. 1, and what would happen to the hotel’s roughly 300 employees in that situation.

“There’s too much movement right now,” he said.

Peter McMahon, Hyatt Regency Dearborn general manager, said he broke the news to the staff Wednesday.

“It was difficult, as you can imagine,” he said. “It was very difficult to have that conversation.”

McMahon said he will be leaving the hotel Nov. 1. He also is general manager of two Hyatt hotels in San Antonio, Texas. He came to Dearborn in May.

He also released a prepared statement, on behalf of Hyatt Hotels Corp.

“It is our hope that the owners will continue to operate a full-service hotel supporting Detroit and the Dearborn area as it has for nearly four decades,” the statement said. “Should there be a lapse in management of the hotel, Hyatt will work with the hotel’s owners to offer assistance to employees.

“Hyatt has been proud to serve the Dearborn and the greater Detroit region for the past 36 years, and we thank our associates, community and partners for their support over the years.”
