My room was occupied by another guest. I paid for early check-in, received my room key through the automated check-in system in the lobby. I used the key to get me in my room. When I got inside I found clothes, suitcases, messy bed, and random stuff sprawled across the floor. Thrash was everywhere and the room stunk. At first I thought I was in the wrong room, but then how did my key get me in the door. I doubled checked the room number on my way back down to check-in. I explained what had happened and was promptly given a new room. This is concerning to me for many reasons. If this happened to these people this could happen to me. What if these people were there and had weapons and thought I was robbing them. What if they were shagging or in the shower. Very scary to say the least. Certainly one of my worst fears come true in a hotel. How did this happen? Doesn't maid service inspect the rooms before they are released to new guests? This was my first time at the Paris, and they have a great hotel but at what cost.
