I just don't agree that a knock on the door after 9 am in the morning is a problem...7:30 or 8:00 am? Sure. From reports, no one is being asked to vacate early. They are knocking to find empty rooms so that they can begin the cleaning process earlier instead of it just sitting there with no guests and nothing being done.
I get that some people are bothered by it, but not everyone is, nor do we have to be bothered by it. It certainly isn't happening with any level of consistency since plenty of us here on the DIS have said we have not had it happen very often, if at all.
I checked with some of my other
DVC friends...not on this message board, and they too have not experienced it to any level of annoyance...a few times, but not more than that.
