We have cruised with P&O Australia before, with mixed results, so we were a little hesitant about booking this cruise. But the price was outstanding and the OBC too good to refuse.
Having just got off the Sun Princess a month before, we were immediately "at home" in our cabin (balcony, deck 11, forward). In fact, on waking up a couple of mornings I had to remind myself were on the Explorer and not a Princess ship!
As they used to say about shoes, our cabin "was well worn, but worn well". Jomon and Komang did a sterling job of keeping everything clean and working well — and were always bright and sparkly as well. The only "fault" we had on one day was a distinct lack of hot water, but I think that was related to a ruptured steam pipe in the engine room that caused a minor emergency.
