The hotel is iconic and everyone at desk and check-in was amazing with so many holiday events happening. Only 3 elevators worked and rooms were not ready upon arrival for some in group. Keys lost their ability to work daily, but those are not faults of the people. The restaurant was slow, average and overpriced. The service staff did not check on drinks or communicate food times well. It was not because of overcrowding nor understaffing.
