Had a blast playing this and can't wait to play it again.
It started a bit slowly as the PFS NPC guiding our group explained a number of dangers that Pathfinders might encounter. It's a lot of exposition at the beginning of the scenario, but it's good information, especially for players new to PFS.
Hint: players, listen to her and do what she suggests!
The encounters were of moderate difficulty for level 1 characters. In the second encounter, my level 1 swashbuckler was reduced to one hit point, but survived. I believe that was the only serious damage our party took.
Overall, this was a great introduction to Pathfinder Society; fun, informative and not too dangerous. I haven't read the scenario, but I'm told there's a mechanic allowing it to provide a different experience when replayed. I'm ready for another run.
