I guess this is more about my style than the adventure but in my second campaign, Troll Spire was fondly remembered more for the NPC than the puzzle trap. I did have an ace up my sleeve for her funny voice.In fairness, I didn't run it. I just read it and thought it didn't sound like something I wanted to run. I had the knight from town do it while the characters were elsewhere. They ran into the deposed harpies which was fun.
