At AKL we were picked up at 11:30 and were the last stop before heading to the port, so were on the ship by around 1pm, and at Beach Club we were picked up at 12:30 and had 2 more resort stops after ours, so we didn't get on the ship until something like 2:30. Lucky we had a nice big brunch at Cape May or we would have been starving! Basically, I would say your arrival window is likely between noon and 3pm.
