Lindz, I wondered when you were going to post.
From Wikipedia: Hogwarts appears to be the only school of magical arts in Britain...
Hogsmeade, Scotland, UK: Hogsmeade is the only pure wizarding settlement in the United Kingdom and is located south of Hogwarts...
One source, though said Hogwarts was in Scotland.

Too many conflicts - if Hogsmeade is in Scotland, how do they jump from Hogwarts to Hogsmeade (magic??)? Also, the Shrieking Shack is in Britain...
Anyway, question: What nickname does Ginny call Fleur behind her back? *snickers*
