Does anyone know how things work when you have a port of call (Melbourne) but at the same time it is the embarkation for a lot of other cruise passengers? We have a 20 night cruise round trip from Adelaide, Australia. We stop off at Melbourne twice during this cruise, and both times passengers will be embarking (or disembarking) the ship. There are only two tours offered in Melbourne with Princess and those are for people who are disembarking and going to the airport. We plan to leave the ship and explore Melbourne. But, does anyone know the procedure for cruisers leaving the ship and coming back on the same day new passengers are arriving? I know I can ask when board, but I am trying to make a few plans and if anyone has done this please let me know. I'm most interested in how early we will be able to walk off the ship. I called Princess but the call taker didn't understand my question. Thank you!
