Really long adventure, and I likely won't ever run it again because of that. You could edit out the travel to the pyramid to save an hour or two.
The maze with the shifting walls was really fun.
I folded up post-it notes on my battle map to show the shifting walls and the players had a blast.
I would have enjoyed it more if it had been divided into several smaller adventures, like they did with DDAL05-06 Beneath the Fetid Chelimber
and DDAL05-07 Chelimber’s Descent.
