Apologies in advance, this is another long review by me...
We booked this cruise last March while on Sun Princess on a two night coastal between Brisbane and Sydney. We took that cruise for two reasons -- to see if we liked Sun Princess enough to book a longer cruise and to take advantage of the benefits of booking while on board, especially the ability to cancel and rebook with no penalty.
We took advantage of this last benefit twice before final payment was due, saved more than $1500 total on the cost of our BE guarantee and even ended up with twice as much on board credit as we'd originally booked with. Win, win, win.
B227 - standard balcony cabin, very small balcony, decent storage space, small bathroom with limited storage space but god sized shower
