This is one of my favorite modules. It couts as a two hour module but there is such an opportunity for countless roleplay it usually ends up taking around 3. Players like to spend countless minutes playing carnival games, and there is so much to do with so much room for DM spin. The module can also be very unsettling when they encounter the fools. Madness saves are always fun. The mirror maze is amazing at confusing players, and its cool to see a final boss with lair actions at tier 1.
The magic item is not something you see, so i appreciate that. However, it is situational at best and completely useless at tier 2.
