Like many others I read many negative reviews about Britannia but fortunatley I make up my own mind and very seldom listen to others.
This was our 20th cruise with P&O and we have said many times that we have never had a bad cruise, but some have been better than others.
Britannia is a big ship but to be fair you really didn't notice that, part from sea days when the open decks were very busy as are most other ships.
Good size cabin with plenty of hanging space and storage, separate sitting area with bed sofa. Bathroom with 3/4 bath with shower and a glass screen which was much better than the old curtain. Balcony apwas on the small side, you struggled to recline the chair.
