Remember, DD especially didn't want to give a clue to Draco of 
anything Draco couldn't conceal, Occlemency wise, from DEs. So he 
wouldn't have wanted to go too close to Draco's haunts during HBP.

Binns (in COS) said "Naturally, the school has been searched for 
evidence of such a chamber, many times, by the most learned witches 
and wizards. It does not exist. A tale told to frighten the 
gullible." - so many normal areas can be dismissed. 

Nonetheless, DD (in GOF ch23) mentioned to Karkaroff, "Oh I would 
never dream of assuming I know all Hogwarts' secrets, Igor", and 
then described stumbling ontl the Room of Requirements as a 
bathroom, but never being able to find it again. (I remember it 
because JKR said in an interview that referred to a room she would 
like to visit in Hogwarts)

In Hogwarts:

6) the Chamber needed Parseltongue to enter, so DD may not have 
checked there.

7) DD didn't know how the Room of Requirements worked prior to OOTP, 
and may not have explored the section where Draco was working during 
HBP.

8) DD didn't check the Slytherin common room area, although students 
weren't happy with Snape poking around there. Snape may have been 
less effective (on purpose?) at checking their common room for 
concealed areas. (That is an area Riddle would have felt most at 
home in Hogwarts)

9) The tunnels leading to Hogsmede! The Mauanders and twins were the 
only ones that knew of 3 of them. One was blocked off.

Outside of Hogwarts:-

10) LV had giants working with him last time, and they can't 
perceive magic so well. One of their colonies would be naturally 
protected by the inhabitants.

11) I'd still like to see the Dragon santury where Charlie works. LV 
thought anything he was scared of may keep others away as well 
(hence, the Inferi in HBP horcrux location)

As for who can help find them:-

* Slughorn

* the kidnapped Florean Fortescue was very accomplished in history 
and knew his Wizarding families (he helped Harry with his homework 
in POA) -I was wondering why it was important to kidnap him?

* Krum. With Karkaroff dead, a 'friendly' face that is familiar with 
Dark places in Europe may help. It would also be amusing to see how 
Ron/Hermione/Krum coopperate.

* and my favorite suggestion, isn't it time an aussie wizard was 
introduced (stop moaning ... lol)
