I ran this for 3 players last night in high tier. Many of Kaushal Avan Spellfire's comments are spot on (having DCs for the ability to disable some of the items would be nice), but it was definitely a fun scenario. Due to a variety of factors, my table started almost an hour after the slot started, and we still finished 30 minutes before the end of the slot.
The last handout made my wife cry with how poignantly and hopefully written it was. Bravo.
