I tend to get my own luggage any time I arrive after 7pm, unless I'm planning on heading to a park that has late hours. If you land at 9:30, you should be at your resort by 10:30-11. That's when the clock starts ticking!!! So, theoretically, your bags could arrive at your door around 1:30AM!!! Not so good. So, I would do one of two things.
1. get the bags yourself and bring them to the DME bus with you. That way you'll be able to unpack, and get a good night's sleep.
2. tag your bags, letting dme take care of them. Then, when you get to your resort, tell the CM at checkin (even if you had online checkin and you got a room ready notice) that you want your bags held until the next morning. Then, stop off at Bell Services and tell them the same thing. When you get to your room, put out the 'privacy please' hanger on your door. When you wake, the message light should be blinking on the phone. Call Bell Services (or Luggage Assistance, depending on your resort) and tell them you are ready for luggage delivery.
