Princess Cruise - excursion to Australia Zoo on last day

[ArlineLA]

We are looking at 9 Day Queensland Sydney to Brisbane and wanted to include excursion to Australia Zoo on the last day which is arrival in port.  Princess sells an excursion that leaves at 9 am and returns “to ship” at 4 pm. I’m sure we can’t get back in the ship to retrieve luggage that late. Does that mean we take all of our luggage in the excursion bus and it stays on the bus while we do the Zoo visit?  Then the bus takes us back to the terminal?  
We’re probably staying at least one night in Brisbane but does it make sense that they take us back to the cruise ship terminal and then we need to Uber to hotel?   Also, has anyone left their luggage on the bus during this excursion?  Called Princess call center and agent just confirmed we could not get back on the ship but had no idea who the excursion company was.

Usually disembarkation excursion coaches will take all your luggage with you and drop you at the airport after the excursion is finished. The excursions are aimed for those who are taking late flights. You may have the choice of being dropped at the airport or in the central business district of Brisbane. 

 

This link takes you to a disembarkation excursion from Princess (not Australia Zoo) and it states you will be dropped at the airport - Brisbane Disembarkation Excursion
