Not worth what I paid
Overall, this hotel is nice. But, hardly worth the $200 a night I paid on a recent one night trip over to the Houston area for a football game. I had high hopes to stay at the visiting team hotel to truly make it a fan experience. I called numerous hotels who told me to check with the Hilton Americas. I eventually spoke with the hotel manager who explained they are a "preferred NFL team hotel". While I understand they can not tell me who is staying at the hotel, they can certainly tell me who isn't, and they had no problem mentioning that the "Home team" was staying and The Rolling Stones stayed just a week prior. Unfortunately, my team was not staying at this hotel and I was suckered into thinking they were.
The staff was not very knowledgeable about the surrounding area. My wife and I were looking for lunch and led on a wild goose chase trying to find a simple quick meal. There really is not any places to eat (outside of paying hotel prices) with-in about 3-4 blocks. 
Also, for the football game, we were told the metro rail would be the best way to take the cheapest trip to the stadium. The concierge failed to mentioned to us, it is a free ride to and from on game days. Something a random stranger had to tell us after we paid for tickets to and from.
While I found the bed comfortable, the pillow left little to be desired. I simply could not get comfortable as it was like sleeping with my head on a rock. Also, note that the thermostat does not have a "fan on" setting. So, its hard to drown out noise from the hallway. I was startled awake numerous times with people coming and going in the hallway.
Also worth noting, the ice machine on our floor was broken. Not all that big of a deal, but when you pay over $200 for a nights stay you expect things like that to work.
I can honestly say, I feel ripped off. From the attempted fan experience to the broken ice maker. I wish I would have saved myself $150 bucks and stayed somewhere with a free breakfast and free parking.
