Dump in NYC
I have benn coming to NYC for years. I have top tier status with Hyatt, SPG and Marriott. The Grand Hyatt recently was renovated....they should not be allowed to use "GRAND" in the title.iif you are top tier status, listen carefully...THEY DO NOT WANT YOU TO STAY IN THIS PROPERTY!!!! YOUR STATUS MEANS NOTHING!!!! 
I have not even started on housekeeping issues. The bathroom was growing mold. The air conditioner was blowing heat. The rug in the room was so stained I didn't want to walk on it. Hyatt shoud be embarissed in a newly renovated property how poorly it is being kept up. The management knows there are issues and does not care. 
Do not even bother calling the Diamond desk desk with Hyatt. It is a waste of your time. The hotel has plenty of tourist. Save yourself some agravation and stay somewhere else!!!
