What is this 100% satisfaction you speak of? If you are asking me if I was 100% satisfied, the answer would be no. I would probably give you a 65%. Since it is not 100%, I am not sure to what this entitles me. I am certainly curious to see what backs up this 100% promise. As reported before. I was charged for valet parking multiple times for times I did not use their service. It should not be my job to correct that. They should know when I park and when I don't. The bathroom toilet kept backing up. The resolution was to bring up a plunger. I have never had to plunge my toilet in any hotel I have ever stayed in. I did on this trip! So now I can say that the Hilton is the only hotel requiring me to do my own maintenance. The keys to my room stopped working and had to have engineering make me a "Special" key. This should not have occured. 2 of the 4 elevators stopped working which caused massive lines in the lobby and waits on all the floors. This problem went on for 2-3 days. Once again, it should not have happened.
