it was spelled to be  SPECIFIC for Harry - it wouldn't activate 
unless Harry touched it. >>

<snip>I believe it says somewhere in GoF -- when Dumbledore speaks to 
Crouch Jr? -- that great lengths were taken to ensure that Harry 
reached the cup first. This means, as I understand, that if Cedric 
had taken the cup when he deserved it, Cedric would have ended up in 
the graveyard alone.>>

I think Sherrie has something when she considers that the World Cup 
Portkeys were treated in a different manner than typical Portkeys, 
but *not* that they operated in a different manner as Brief 
Chronicles points out above.  My memory is flagging, and I do not 
have my copy of Goblet of Fire handy, but....  I seem to remember 
that Mr. Weasley and company handed over their Portkey to the World 
Cup officials when they arrived at the Cup's venue.  (Or did I just 
assume that because they did not use the same Portkey to return?)

Anyway, if they did hand it over, then wouldn't it be reasonable to 
suppose that the Portkey that they used for their trip to the Cup 
could have been used to return them to their starting point?  
Remember, there was quite a lot of confusion due to the Death Eaters 
and the Dark Mark when they left.  So the presiding officials may not 
have been as efficient as they normally would be and created Portkeys 
in a more willy-nilly fashion to send people on their ways!

Has this been mentioned?  If so, I apologize!
