Bed Bugs.
Stayed in a room on the 11th floor, got back to my room at 3am and the bed was covered in bed bugs. I killed a few, while waiting for the manager to come up to the room. He said, "Maybe they're mosquito's." I said "REALLY? Pull back the sheets" there were 3 large ones on the sheets. He said, "Well we're closing in 7 days. So we'll put you in another room." It was so gross and he did not seem surprised at all. He pulled back the sheets and the mattress pad and more were there. Just gross. In the morning the manager would not come down to speak to me, he sent a security guard to take a report. I could not be more disgusted. 1st day of a 5 day trip and now I need to find a laundry mat to wash my clothes.
