We could not wait to get back on a cruise after waiting 3 years (the Australian Govt made us wait and wait for cruises to restart) and booked as soon as we could.
Embarkation - The Sydney Overseas Passenger Terminal is a great facility and the process was reasonably quick and well executed.
Stateroom - Balcony cabin on deck 9. Standard cabin - good storage, very comfortable bed, small bathroom. If you are participating in cruise activities then no worries if your cabin is on the small side.
Look, if you are really enjoying your cruise then you won't spend much time in your cabin anyway. A standard cabin is not huge (I do not know what the suites are like) so don't expect it to be. For 2 adults it was fine. There was a good amount of storage and hangers (though I took extra) and there is a sofa as well. The bathrooms are small, but they have a shower, a toilet and a vanity - all that you need. I do wish they had an exhaust fan as they do get very foggy. I like a balcony as you can experience some fresh air and have the curtains drawn back, which is really nice.
