What are the successful cases of well-known hotels using public relations?

Ritz-Carlton pays attention to service and service remuneration, and public-private relations should be good.

Personally, I feel that all international hotel chains have used public relations to some extent, which can be said to be successful, such as Hilton, Shangri-La and Holiday.
