We've stayed at the Hilton and the Marriott. The Hilton has an impressive lobby area. However, the standard rooms are not that nice. They are in a real need for updates. The bathroom, especially, is in bad shape and can only really fit 1 person in there at a time. I had some difficulty helping my small DD in the tub as I kept banging against the toilet (ugh!

). The tiled floor had brown stains that kept having brown liquid come up. The tiled walls had brown grout all over. I had to line the floor with towels so we wouldn't step on that brown muck. The area where you would stand to have your shower had a vent above that kept dripping water down on you. We complained to the Front Desk who were indifferent and kept telling us that all rooms were the same.
I read some of the Tripadvisor comments on this hotel. I noticed that a lot of the positive comments came from people who stayed on the Executive level. Those who were in standard rooms and complained about the room's weary state and bathroom yuckiness were pretty much identical to my own complaints. So, hopefully, you are on the Executive level.
The Marriott, on the other hand, is fantastic, with comfortable standard rooms, and had very attentive staff.
