Combining the beauty of the city, and the snow you're seeking, I would recommend you to go to Edimburgh! Have you been there already? Also, you could go further north to see lakes, castles and mountains. I have been there just in Summer, but I am sure it must be wonderful in Xmas time! If you go there, please, be sure to send us some pic!
