Heidi:"I am sure there has to be a way to bring Muggles into 
Hogwarts - squibs can get in, so why shouldn't Muggles be able to?"

There's been guests at Hogwarts, including parents of the Champions 
in GoF, and nothing said they were all magical. Also, IIRC, 
Hermione's parents made it to Platform 9 3/4, and they certainly have 
been to Diagon Alley.  Probably Muggles just can't get in to magical 
places on their own.
