One thing I really feel the need to clarify. The home we live in isn't any kind of mansion, but it's a nice home, and I'm obsessive about taking care of it. It's my personality. Which in turn, means that I am obsessive about taking care of other rooms that I stay in. Other than changing out towels or making the beds, the stateroom hosts and housekeeping NEVER have to pick up after me.
Along with that, I would never do anything to damage the property of others.
If my over the door hanger was going to cause the door to not close, or if it was going to scratch at the top (yes, I think of those things, just as I would in my own home)
I wouldn't use it.
But I'm glad to have caught this thread, because I hadn't heard that DCL was asking us to not use them. Since they've asked, I will no longer use one.
