Art here: 

I am also convinced on the last point. Someone, Voldemort, Harry, 
Hermione, Neville, Luna or maybe Ron (although he's the long-shot) 
will figure out a way to apparate in Hogwarts. 

Question regarding house elves. If there IS no 
apparation/disapparation in Hogwarts, what do house elves do? (think 
Dobby snapping fingers and then he was gone) Do they "shimmer"/"orb"?
