Staffs are very problematic
Had some bad experiences.
1. Guys. You should not lie.
I am a gold member and I requested a space-available upgrade to exec floor. The first employee I met told me that the night is full book, so it cannot be done. Because I did not think it was busy time of the month and week, I requested again to higher manager. And suddenly a room appeared. I would not think that you guys gave me a booked room. No way.
I know that it is more convenient to just lie that you are fully booked, but pleas lie all the time consistently or don't. 
2. It took about 30 min. to borrow a flash light. 
I know I am not supposed to borrow one, but employees in the front were very negligent about how much it is going to take for their security to bring one. One woman was almost very rude and did not care about anything out of her job description.
3. Breakfast area smelled like a towel that's not been properly dried. You know.. the smell of water gone bad.
Only thing that was nice was door men who did their job.
The front desk employees should learn about the upgrade policy of hilton honnors, and general attitude.
