Hotel McAlpin with its own orchestra and hospital 2 weeks ago Near the end of 1912, when construction was nearly complete, at 25 stories it was the world’s largest hotel. The Hotel McAlpin was designed with 2 gender-specific floors and a floor dubbed the “sleepy sixteenth” for night workers. On Christmas Eve 1916, a 19-year-old was sexually assaulted and beaten by an attacker who had rented 2 rooms on either side of his suite to muffle the screams. The amenities of the Hotel McAlpin were as breathtaking as they were opulent including a massive Turkish bath and plunge pool on the 24th floor. The hotel also had its own in-house orchestra, as well as its own fully-equipped hospital.
