We have a 9:15 am PS for Crystal Palace at the MK for the day of our flight (Monday, 11/1). It's a Southwest flight that leaves at 2:00. What time should be make sure we're heading out of the park to get to the airport without going crazy? Also on a side note, has anyone ever dropped part of the party off at the Southwest curbside check-in and then gone on to return the rental car? We're renting from National so I was wondering if this might be a help in getting good Boarding Passes for at least part of the party.
