We chose a 3 night Sydney - Burnie - Melbourne cruise as a sampler and introduction to Cunard cruising.
Embarkation was reasonably painless. We arrived a little earlier than the allocated boarding time and was told to board anyway. We dropped off bags, queued for about 15 minutes and then found ourselves on-board. Finding our cabin was easy as we were escorted by our cabin steward who did a good job of explaining our cabin facilities.
The cabin was comfortable and clean, though no larger than what we've previously experienced. Power is via British and American sockets, which is no problem, but there were no USB sockets. The bathroom was small but everything worked as expected. The bed was comfortable, but I found the pillows too soft. A nice touch was a complimentary bottle of sparkling wine on ice in the cabin. As a tip for Cunard though, next time source a wine that is drinkable.
Average size, clean and comfortable, everything worked though a little dated.
