NOt sure why you have white tags...no tags are needed for departure. In any case, your flight info does not have to be listed.
When you get to MCO, or even to your resort later in the day, you might want to be sure DME has the correct flight info (times/airline) for your departure from MCO at the end of your stay. It really doesn't matter what flight you arrive on....they see those yellow tags on the checked bags and they are pulled out for resort delivery...as long as it isn't between 10pm and 7am.
It is the flight home that is important as far as times go. It is this flight that gives them the pickup time for your return to MCO.
