Checked in fine. Room was ok but chilly. I adjusted heat and we left for several hours. Upon return, the room was cold. No display on heating unit. Called front desk and gentleman arrived promptly. He could not fix unit so we were moved to another room. That was just fine. But, what happened at 4 am was NOT fine! At that time, my husband was woken up by voices in hallway. Then, he heard the door lock click. Then, someone tried to come in. Luckily, we had the safety lock on. My husband slammed the door shut. We were scared to death. There was little sleep happening after this happened. When we told the hotel clerk what happened to us, he apologized and said he gave someone our room! At 4 in the morning! We understand mistakes happen but we were really traumatized. A mistake like this could have had terrible consequences (they could have been shot!).
