The Faire Favors achievement is available during the Darkmoon Faire on Darkmoon Island.

Details
You must complete the profession-based quests for every one of your professions. Everybody will need to do the secondary profession quests (Fishing, Cooking, Archaeology) in addition to your two primary profession quests. Most quests can be done without leaving the island, but a few require you to leave to do simple tasks.
