I read it too, well as much as I could stomach.
Harry says Charles always, always called him "Darling boy".
Speaking of the time after Diana had died he said that he and William worried about their father working too hard on all his projects and patronages as they would often come down in the morning to find him in his office asleep with his head on his desk but that Charles always had dinner with he and William and wanted to hear all about their day, would always come up to tuck him into to bed, read to him and always made sure there was a nightlight on as Harry hated the dark. He would leave little notes on Harry's pillow telling him how much he loved him.
I'm this won't change your mind at all @LividSun but they are Harry's own words.
As for the nonsense about accommodation Harry isn't a child he's a 41 year old man, 41! He would know that staff would have to be arranged for his stay, he was given a deadline to respond, he let it pass. Either respond in time or make your own arrangements. That's just basic manners.
