Firstly let me say that our last P&O cruise was 10 years ago and we vowed "never again". However we needed a mid year break this year and the only ship sailing out of Brisbane was the Jewel.
I fully expected a ship that was very run down, with 1980's overflowing public toilets after reading the reviews here.
We had two cabins - a deluxe balcony and standard balcony. Both were spotlessly clean with plenty of storage. The deluxe did have a better size balcony so I would definitely recommend that one.
