Probably all true. And, yes, I agree that I am little crazy!

Kudos to you for noticing! LOL!

I do live in my own little bubble where, although I am aware that the worst may happen, I still try to do whatever I can to help for the best.
I am just hoping that if housekeeping staff were wondering when we were leaving (and yes I would let them know the day before, as well) and came by early, they MIGHT NOT knock if they see the note. They may knock anyway, but perhaps some kind people would pass me by and come back later. If not, no harm done by leaving a note. I completely realize that it might not help, but I will feel that i did what I could to make my life, and perhaps theirs, a little easier. I know that they can enter my room with the Room Occupied sign up, but if I am sleeping I really would rather that they didn't knock. If they ignore my requests not to do so, there isn't anything that I can do about that. I can still ask them not to, though, knowing full well that it may not work.
It is good to know in advance that this is a possibility. I am not a fan of this policy, but as everyone says, I can choose to stay elsewhere. If I do stay at WDW, it is easier to not be upset when I am prepared for this to possibly happen. I love the knowledge and wisdom shared on these boards. It helps to keep a positive attitude when you have information up front so you can be prepared.
