I guess I am a little too oblivious when it comes to my travels. I know I should assume the worst, but I would think all the doors are secured after a room cleaning, between guests, etc.
However, assuming I was a bit brighter about things and checked the locks upon entering, isn't it surprising that the patio door is unlocked?
Like another poster said, I don't actually use the patio doors when I get a room that has one. When I get ground floor rooms, most of the time I'd get a window that was locked to prevent anyone from opening it (from inside), or a limit to how far it could open.
I've read reviews of this hotel via the search function. After staying there this past Oct, yes, I can say the area may be scary to some people, but wouldn't that prompt the staff to be just that more aware? Again, I probably assume too much from my hotel?
