It's quite extensive. The DM who wrote this has gone over and beyond what was needed, even rewriting backstories of some major and minor characters. Still, it's an amazing resource. I am currently in the process of adding an orphanage across the street from the Church, putting the third night hag there as the polymorphed headmistress, and the bones of St. Andral have been moved to Old Bonegrinder and NOT the coffin maker. This is going to give the PCs more time to wander around Vallaki and discover the cool stuff going on there without triggering end game events yet. I still want to use the coffin maker's shop, I just won't have the bones hidden there.
