No I don't think he was, but she was marrying into a family that mostly did enjoy blood sports and country life.. their leisure time, their lifestyle was Edwardian, with the traditional emphasis on country house living.. house parties for shootng, hunting etc. And at the time of their marriage, the RF were pretty much expected to spend a good deal of their leisure time together whereas nowadays things area lot more flexible. Plus Charles DID enjoy the Balmoral routine, the hunting etc etc. If Diana did not like any of this, and I don't think she did, she was letting herself in for a lot of boring weekends and times when the clan were all gathered at Sandringham or Balmoral.
