zgirnius:
Harry, of course, does have an Invisibility Cloak, and used it to 
follow Draco around. As did two House Elves Harry commands, who can 
also be invisible, or at least magically unobtrusive... And Harry still 
did not figure it out. 

I do not think that this is because Harry is stupid, but because of the 
magical powers of the Room of Requirement. The only way Harry (or a 
House Elf, or Snape, or Dumbledore, to name all the other interested 
parties) could get into the Room was to know the purpose of that 
version of the room which Draco is using. 

For example, Draco can get in in OotP, because he thinks to himelf, he 
wants to get into the classroom of a secret DADA club. And presto, he's 
in, because he is 'requiring' the right thing. But Harry tries all 
sorts of variations of 'the room Draco is using', and that does not 
work because Harry does not specify the purpose of the room.

He finally stumbles into the right version unknowingly, when he runs 
there to hide the HBP textbook. Because at that moment, he wants the 
right version of the room-a secret place to store something. Since 
Draco's not in there at the time (he is of course in the infirmary), he 
does not even know it. 

Trelawney happens to need the same version of the room (to hide her 
bottles of sherry) at a time when Draco IS in there, so she gets in 
too. But of course she knows none of the context, so it does not mean 
much to her either.

I don't see why Dumbledore would have had any better luck.
