You love luxury, so what about Switzerland? Diamonds and skiing are high up on your wish list, after all.
India also calls you as you appreciate tradition and Imperial British history. Even parts of Mexico are a draw.
Cities like Delhi and Brussels have you hooked- indeed anywhere where great administration is centred.
It may even be Orkney or Shetland, or somewhere out of the way, that excites you and hill walking will give you that feeling of being part of the great outdoors as well. Wide-open spaces also appeal greatly and you're not averse to cramming everything into a backpack and taking off either.
