Given the urgency of an extremely important NPC to the city missing and possibly dead... my party (and I agreed) logically wanted to rescue him as soon as possible. That meant we had to go through the first area (water and caves) through a bunch of weak fights, then through the habitat module (again more trivial encounters), and then through the ship area to find Khonnir. It's a lot of fighting that was expected to be broken up but made little sense to be broken up.
Also, the whole Silverdisk Hall event we skipped because of the above. I think this would have been a neat thing to have done but we did not spend a week in town and we're not going to go gamble when a man's life is at stake lol.
I think this adventure would have benefited greatly from better pacing, a more engaging town (additional quests/interactions/exploration), better designed encounters,
and less emphasis on ridiculous DCs for less tech oriented characters.
