Just go to the front desk / concierge of the resort you are staying at. You will need your confirmation number, but they will be happy to print out boarding passes for you. We have never left that early on return trips, but have done the boarding passes at the 21 - 22 hour mark, and still gotten low B passes, still not bad. Are you flying in and out of PVD? If that is the case, that early flight is typically not booked, so it is even easier.
