If we were arriving that late, I would want DME to deliver our bags the next morning, rather than having to deal with them ourselves that night.
We would have carry-ons with everything we need overnight (including tooth powder). We would go directly from the arrival gate to the DME Welcome Center. We would not waste any time going to and from baggage claim and waiting for our bags to emerge on the conveyor. We would not have to deal with our bags (except for our little carry-ons) at the airport or at the resort. We would be on the first motorcoach to our resort, rather than risking the very real chance of being on a later motorcoach. The next morning, our bags would be delivered, with Disney paying the inbound tip.
I realize that some people don't agree with me on this.
