But I'll be honest, the times I've complained and asked engineering to come fix it, most of the time they can't really do anything. As you can imagine with people staying night after night after night hair and whatever gets into the drain and there's really no way to fix it easily. I think if you didn't take the room change you're out of luck – it's certainly not something I would ask for some serious compensation about, especially if I've been offered a different route. It may be just at the plumbing there doesn't work very well until they do some kind of overhaul it's not going to change.
I also wouldn't assume that no one went to try to address it – it's just if they can't just pull a lot of crud out easily they won't do much else.
