They should rather have dedicated it to Tatiana's bisexual uncle Grand Duke Ernst Ludwig. Unlike her he actually holidayed on Capri, didn't he, as a guest of the bisexual (by our modern standards possibly pedophile?) industrial magnate Friedrich Krupp? Though I guess that wouldn't be as romantic.... Neither would a room dedicated to Tatiana's cousin Grand Duchess Maria Pavlovna, Princess of Sweden, who claimed she had been abused by her mother-in-law Queen Victoria of Baden's own Rasputin figure, Dr. Axel Munthe, during a Capri sojourn...
As Axel Munthe himself noted in "The Story of San Michele" the shadows are as darkest where the sun shines the most brightly....
