Okay, first make sure to tell the Front Desk you do NOT want your luggage delivered that night. It’s highly unlikely anyway, since Luggage Assistance closes at 10 PM, but just to be safe, also put the “Privacy Please” card in your key slot before you go to sleep. In the morning, if your message light isn’t already flashing, just press the button for Luggage and ask them to bring it up. Remember, DME takes care of the tip, so you don’t have to.
DisneyHumbug, I don’t know where you’re staying. If it’s a Value resort, the above applies to you, too. If you’re staying at a Moderate, Deluxe, or
DVC, you want to take the extra step of letting Bell Services (which likely WILL be open all night) know to hold your luggage until morning. If that’s the case, your luggage might arrive slightly faster than Disneynut’s, only because that’s the way service is set up.
