We just got off the ship on Sunday and the testing and waiting for results are indoors.
But waiting to get to that testing area was outside (pre-port arrival time). They had two lines one for arrival times that were on the hour/half-hour and one that was for 15/45 minute arrival times. Meaning 10:15 PAT were against the building, 10:30 PAT were closer to the street. Once everyone from the 10:15 PAT entered the port, that line turned into the 10:45 PAT line. It wasn't really clear with signage, but they did have cast members there to get confirmation on what the lines were for.
