I didn't go fishing for any, they sent me the free-night cert proactively. Interestingly, in the fire stairwell there were loud audio attenuators going all the way down -- a recorded voice proclaiming an emergency combined with honking tones. But in the accommodation corridors themselves things were dead quiet, and AFAIK no effort was made to contact or evacuate upper-floor guests. It's not how I would handle a building fire if I were in charge.
