It all depends on the style of play to get through the game. If you want to blitzkrieg through the game - to get the No Regrets Achievement for instance - then it shouldn't take too long at all.
If you want to finish the DLC in low chaos and would like to get Whisper Ways and other related Achievements then it could take some time to finish.
Play through it twice in different styles if you really want your money's worth.
