My family is flying home from MCO on September 3rd on Delta. Our flight leaves at 6:20 am. I know that DME leaves 3 hours before and we need to be there 15 minutes early. How does that work with check-in on the flight the night before and checked luggage? Normally I let my husband deal with this, but he is not going to be on this trip so it's all me. I know that Disney can check us in the day before, but what about paying for checked baggage? Can we still deal with our checked baggage at the resort or are we required to deal with it at the airport because of the early flight? Thanks for the help!
