Business trip
I stayed at the Hilton Palacio del Rio for business mid September. The location was excellent due to the fact that the show I was attending was directly across the street at the convention center. Also very convenient for strolling the riverwalk. 
Rooms were adequate and clean. There was a key coded safe in the closet, but being that I'm short, it was a little hard to reach because it was on a higher shelf. I needed to grab a chair to make sure I had emptied it before leaving.
Wifi is not available in guest rooms which I found to be a nuissance. To get wifi, you needed to be in the lobby and it was spotty. Not what I expected.
My first night there, there was a band playing right outside my room. Even though I was on the 16th floor, I could hear it very clearly. Thankfully they only played until 10:15-10:30.
The elevators had a set up I haven't seen before. You need to choose your floor before entering the elevator and it will announce which car you need to enter to be taken to your floor. There are no buttons inside the elevator.
The light for the closet was motion activated. Not a bad feature for middle of the night restroom visits.
