If they got to live at Windsor Castle, would they still have gone to CA? Or did they remodel Frogmore only to ditch it ten minutes later and move to "punish" the Queen? Did they really think they could maintain Windsor and a Hollywood connection? Glad they couldn't get Windsor. They'd have remodeled it resemble the Magic Kingdom.If you remember, they wanted to live at Windsor Castle. The Queen said NO.
So they obviously don't mind about age, it's just not GRAND enough.
