I was just wondering will resorts hold onto your luggage after your "check-out" time??

Here is the deal, for our trip we are taking a late late flight back home--something like leaving Orlando @ 10. Our hope was we would put our luggage tags on our bags & leave at the hotel while we spent our last day @ WDW. Then we would for the airport and the ME would have the luggage all set and taken care of...Is this possible??????
