Timeline Glitch
This movie is incredibly well done and re watchable except there's one thing that really bothers me.
Molly emphasized to her brother that they were landing at midnight. Josh's initial flight was delayed/skipped so he ended up on Molly's Flight. When they land, the whole family is there and it's daylight. They have a party, take them to the apartment and THEN they jog to see Molly's brother. They would have been awake for close to 36 hrs by that point.
Too much happens before they address the sleeping arrangements.
