GoF: Beauxbatons and Durmstrang? And what of the ship?

No: HPFGUIDX 30934

As I was reading "Goblet of Fire" earlier on, I realized that there 
is no mention whatsoever of any of the Beauxbatons or Durmstrang 
students attending a class. As we know that there are more 
Beauxbatons students than just Fleur Delacour, and more Durmstrang 
students than just Viktor Krum, do they simply not attend courses? Of 
course, if they did attend at Hogwarts, they wouldn't be in year with 
Harry and friends, but surely there would be some mention, would 
there not?

Of course, there's also the matter that with the headmasters all at 
Hogwarts for most of the year, how are the schools handling? There 
seems to be no mention made.

Also, we know that the Durmstrang ship surfaces and stays in the 
Hogwarts lake, exactly where the second task is held. Yet, there is 
no mention of it being gone *or* of it being there.

More than anything else, I think I'm looking to see if anyone else 
noticed these things.

Thanks.
