Try pulling up the dungeon finder and clicking the tab that says "random dungeon", it
should have another choice come up that says "specific dungeons" or something like that.
Click it and uncheck everything except for the one you want. The queue. You should get
into that one. (:

To get to the place is u go to stormwind city and look on your map. But now its harder to
get there because of the cataclysm. Hope this helps.
