Curious on room occupied/DND signs -- what can we put up on door?

[happymommy]

We had a phone call several days last week when our sign was on the door. We don't get out until noon or later, so they called my cell phone and asked when we wanted service. I just told them in an hour or so, and they were fine with that. No one ever knocked.

So not to hijack the thread, but any experiences (positive or negative) with napping babies? My 1 year old generally naps around 1:00. I would be crushed if a loud knock on the door a few minutes into her nap woke her up. We always bring a noise machine when we travel with the kids, so hopefully that will block it out.

There is a thread that has guest experiences with this new process on the main resorts page. There are a couple people who have had problems with napping kids but also some who haven't.
