Probably not. But, as I've said...I have had housekeepers leave a tip on the sink, for days. There has been a note left so the housekeeper knew it was for her/him. But it wasn't touched. I have talked to the front desk and have been told that housekeepers aren't supposed to be tipped. They make a decent (note I said decent, not great) paycheck.
And that's the issue. Why do some get tipped, while others don't? Why not tip a bus driver that gave you some really outstanding service? Because Disney feels that outstanding service should be the norm! And the funny thing? I have seen posts from people that say they never tip housekeeping when they aren't in WDW!!! But they do there. Why? They want to make sure they get towel animals. For some reason, they seem to think that their rooms will not be cleaned good enough if they don't leave a tip. And to me...a tip is to acknowledge outstanding service. But, a lot of people disagree with me.
That's what CM friends have told me as well. But let me ask you a question....what would you do if a guest came up and wanted an upgrade (and you hadn't been planning on giving him one) and slipped you a twenty? Do you keep refusing it? Those tips that may have come your way...did they come as a result of an upgrade that would have happened anyway, and was basically unasked for, so the tip was just a 'wow, that's wonderful, thanks so much' kind of thing? Just curious.
Disney is very clear on what their tipping expectations are. There have been a lot of books/articles written by former CMs that have things in them that Disney may not agree with.
