Stayed here a couple of weeks ago for two weekday nights. Generally try to stay away from Times Square, but since I planned to see a couple of shows, bit the bullet and booked here. Also, generally did not have great impression of Marquis from stay a number of years ago (and the dreary lounge back then). However, I feel like my stay was pretty decent. Did the job. While not luxurious, room was very satisfactory. M Club hours are as posted several posts above. Evening hors d'oeuvres are really nothing to get excited about, but breakfast is as good as it generally gets in the US, as the lounge guests share the same breakfast buffet as the paying restaurant guests. Excellent breakfast, which for me is a big plus. And, for better or worse, I appreciated the elevator system this time, which really works well IMO. No long waits or crowded elevators with no space to get on.
