We're arriving at MCO around noon on a Saturday and staying at a WDW resort. We are planning on using ME and I know they will collect your luggage for you but I'm hesitant on not having my luggage with me or making sure that the airlines didn't loose them. So, we exit the airplane and head over to the shuttle to the main airport building. At that point, do I head over to the B side of the airport and down to Level 2 to collect our baggage? How do I know for certain that my luggage will be on the B side? We are flying in on Southwest. Thanks!!!
