Arriving that late I would get something near MCO.
Your right, you can check in everyone while he is returning the rental. He will have to have a photo-id to get back into the terminal. Then you can take him back to the CM that checked you in, don't have to wait in the line again just wait near for the CM to finish up who they are checking in currently, then they will give him his KTTW card. I have heard that some CM's will just give you your husbands KTTW card, but that doesn't normally happen.
