The fact that our room never got cleaned, just restocked. We had two beds in our room, and only 1 bed got made the entire time we were there. Really strange.
Also, we went to the pool, and because our room was located really far from the pool, we had tracked in dirty water into our room, because our slippers were wet too. The floor never got cleaned.
The situation with locating an iron was really annoying. We asked for an iron the first night of our stay, and the front desk was unable to locate one our entire trip.
Another evening, at 6pm, a security guard knocked on our door to tell us to keep our music down, when it wasn't loud at all (and only 6pm in LAS VEGAS!). The guard heard the music when I opened the door to my room to get something out of my car, because I said hi to him. Then he knocks on my door 5 mins later, and tells me to keep the noise down, when it was barely audible in the room. When I went outside the room to see if I could hear the music with the door closed, I couldn't, unless I put my ear right up to the door like a creeper. Mind you, there are several questionable people who lurk around the hotel, trying to sneak into the pool area, and have arguments in the parking lot at ungodly hours, but nothing is said to these people, who I am sure aren't paying customers.
The location, the pool, as well as the front desk staff were really nice.
