Input: When we got checked and arrived at our room the first thing we noticed was the light didn't come on when we flipped the switch upon entering. The room was not very clean at all. Dust had collected on the back of the tv and on the stand behind it, on the window sill and stains on the carpet. We had requested wireless internet service but it was down the entire first night. The mattress was very hard making for an uncomfortable night. The jacuzzi was out of order also. When asked to be moved to a different room we were informed that there were not others available.

Output:
negative
