We just ran this and had great fun! We were a 6 man party (of lvl's 1's and 2's), and even though we're mostly a bunch of combat optimized killers, we almost didn't participate in combat for the entire scenario. And we still had a blast!
The scenario seemed very well written with lots of opportunities for roleplaying, and many active choices for the players - which had real impact on the way we dealt with the different encounters. That was really cool to experience. And even though we are, as I said, quite combat optimized, we had a great time. It was clear from talking about it afterwards, that we could have focused more on combat if we had wanted too - and that at least one fight could have been lethal (as we like it), but we simply chose to take a different route than combat.
