I was woken up after midnight by someone unlocking my door with a key card. Fortunately, I had locked the deadbolt which kept them from getting in but it didn't stop them from trying to force the door open. I yelled at them to back off that the room was occupied. A few minutes later they were back with the night clerk trying to force the door open. Again I yelled at them to back off, the room was occupied. The night clerk ordered me to leave my room as though I had broken into it and to come to the front desk immediately. He kept repeating that order after I said I had to get dressed first. It turns out they gave the same room to two sets of guests. Instead of fixing the problem, I was told I was in the wrong room because I used a third party to book my room and that I belonged in another room. I refused to pack up and leave my room in the middle of the night. At that point the clerk finally changed their system to show me in the room THEY had assigned to me. When I went back to my room to go back to sleep, my key card had been deactivated and I couldn't get back in. After that was finally resolved, I never received any sort of apology for having put me through a very upsetting ordeal. What if I had not engaged the deadbolt lock? Or if it happened while I was out to dinner but all of my stuff was in the room? The night clerk, even if he didn't cause the problem, should be sacked for how he handled it. This hotel is not a safe or secure place to stay!
