I guess I'm not being very clear. What I should say is
I think that,
their first clue instructs them to fly to Hawaii
and if the flight has enough seats available
and if they are not restricted by production from taking a 6 am flight,
all teams will have no trouble catching a 6 am flight.
Shadow times will be coming along in a day or so. I'm not expecting any team to have a check in time later than 4:30 pm.
