Sleep No More is an incredible production: an immersive live performance staged on an expansive five story set inhabiting New York’s abandoned McKittrick Hotel [I have been informed that the bit about the set being built out of an abandoned hotel is just PR fluff… SNM actually takes place in a warehouse scratch built to look like an old hotel. The more you know]. I don’t need to sing its praises. Other folks have done so amply, effusively, and more successfully in other formats. Just Google it.
