I arrived landside at MDW (Midway) just after midnight. You could hear a pin drop. There are a few seats mid-terminal, but a run of seats on either side of what reminded me of a football field, as I walked from one end to the next. Plenty of single seats if you enjoy sleeping and nodding out. There were plenty of people (me included), that were able to lay across several seats and take a nap. MDW does have bathrooms landside. Passengers started arriving around 3:30 am for the morning flights. Don't forget to set your alarm, just in case.
