All the Danish sources I checked seem to refer to it as just "Palace Hotel". English-language sources are scarce; Radio Times calls it "the historic Palace Hotel". I don't think it's quite that obvious that this was a grammar error; compare Trump Tower or Tower Bridge. Huon (talk) 20:10, 5 September 2017 (UTC)[reply]
