I died a bunch of times trying to get into the Western Plaguelands shrine, but the exp when completing the quest was worth it.
The maps you posted are from post-Cataclysm. Not as accurate for Classic.
For what it's worth it seem's to have ended. Tables lay empty with no food spawns last night and as of this morning no tables. As per Retail the event is still on, just looks to have ended on Classic prior to the official(?) date of closing.
