Ended up playing this the other night with a group of 4 players. It does require some prep work , but not to much. Rather then a straight forward story it gives you prompts to make up your own. I crafted something with a combination of the suggestions. The sense of exploration is pretty fun, lots of rooms and things to explore. However my players didn't reach about half of the locations on the map. I could easily run this again and have it turn out completely different. I had beginner players as well as experienced, and everyone had fun. Overall really great adventure, definitely recommend!
