I booked 14-day HAL Auckland - Sydney cruise https://www.hollandamerica.com/en_US/find-a-cruise/P3H14B/N316.html Its last ports of call are: March 9 Melborne 8:00-18:30; March 10 At Sea; March 11 Sydney 7:00. Since I need more time in Melborne, I am thinking to disembark the ship on March 9 in Melborne. What arrangement do I need to make in order to leave the ship before its final destination? Thanks.
