Let me start: So basically I was in really cheap, crappy hotel which had a pool but the walls around it had some really bad mold. The first room I got smelt like cigarette smoke and the sheets had stains all over it. The second room was MUCH better thank god.
I have stayed in one brand of hotels most of my career because I love them but at one point a showerhead shot off into my back and a laser-beam like steel-cutter of water tried its best to cut me in half before I got out of its way. It was like a shower head on a ball joint with a pinhole in it. I really hope they changed their shower head design after that.
