Ah Oriana. I love Oriana mrsmopp but sadly she has been sold and next year will be the last year under P and O ownership.
She is a lovely traditional ship with a wide wraparound promenade deck. There seems to be lots of space inside so the ship, even when full, doesn't feel crowded.
It has a nice calm sort of atmosphere on board, as I guess those people of a more lively disposition would probably be on one of the bigger ships. We liked the cinema (which not all ships have) on sea days if there was a film showing we wanted to see. Also the soundtrack is not too loud, unlike cinemas on land which I find deafening!
I guess one drawback is that cruises on Oriana are a bit more expensive than the really large ships, but we feel it's a price worth paying.
We have got one last cruise booked on her for next Spring!
