Judith, I've read that some people, when they arrive at MCO, insist on collecting their own checked luggage and personally taking it on the DME bus. So if you don't have any (regardless of date printed) ME tags, I believe you can do this. What's important, is that DME knows to pick YOU up. If your travel agent has given them your revised schedule you should be fine. BUT, if you want to make sure, call your resort for that first night and have them connect you (or give you the number to call) for ME and speak with them directly.
