Stay Awhile and Listen

It was driving me nuts not knowing which dungeon had what and since I wanted to minimize my time spent doing these, I made this list:

Quest Dungeon
The Soulcutter Auchidoun [H]
The Cure for Death Auchidoun [H]
Cro's Revenge Bloodmaul Slag Mines [H]
Time-Lost Vikings Bloodmaul Slag Mines [H]
Cenarion Concerns Everbloom [H]
For the Birds Everbloom
Titanic Evolution Everbloom [H]
And No Maces! Grimrail [H]
Cleaving Time Grimrail [H]
Cold Steel Grimrail
Feeling A Bit Morose Iron Docks [H]
The Brass Compass Iron Docks [H]
Shadowy Secrets Shadowmoon Burial Grounds [H]
The Huntresses Shadowmoon Burial Grounds [H]
The Void-Gate Shadowmoon Burial Grounds
Gloriously Incandescent Skyreach [H]
Aviana's Request Skyreach [H]
Family Traditions Upper Blackrock Spire [H]
Oralius' Adventure Upper Blackrock Spire
Damsels and Dragons Upper Blackrock Spire [H]

This achievement name is a reference to the Diablo character Deckard Cain, who always greets the player character with the phrase "Stay Awhile and Listen"

You can accumulate many dungeon quests across the week if you do not have time to run the dungeon daily. The npcs which offers the quest will appear in your inn to let you turn in the quest when you finish them even if he/she is not 1 of the 2 featured npcs of the day. You will find them hanging around in the inn, sometimes upstairs in the 2 bedrooms.

(11/23) Edit: I got a lvl 1 inn on live and found out the non featured npcs can appear behind the inn for you to turn in quests. If they're not visible, relogging resolve the issue for me. For lvl 2 inns and above, they can be found upstairs in the bedrooms or down in the cellar.

(12/9) Edit: This still works after the inn quest hotfix. However you must kill the respective last boss of the instance as it is now a requirement for the quest to complete. The quest log does not correctly show the requirement for killing the final boss of the instance in the inn quest, as such it may be misleading for quest to show as complete if only the item is looted.
