Where is the coolest?

i am living in South Africa But this winter i want to travel to UK to see the snow. Where is the most place I should go to?

Scotland is the most likely but we're talking British weather so that might only happen one Thursday afternoon with deep snow in Cornwall the following morning.

As Fred said, if there is snow (we've had some years without any snow at all), Scotland is the place to go, the further north, the better the snow - Inverness is a good place to start from.
