Just back from the Fantasy. The email we received said they started at 11:30 but we checked in at the airport at 9 and were put on the first bus which arrived about 10:15. My PAT was 11 AM group 3. When we got to the port they let you off the bus then scan your
DCL check-in qr code. Then they scan your safe passage qr code. After everyone is scanned in they lead you to the testing tents where you are COVID tested and wait for your results. Just like in the past if you arrive after your PAT you pretty much just walk right on the ship! If they haven't called your boarding group yet then you will just wait in the terminal until they do.
