I have read many reviews of the Oceana prior to my (first) cruise. I booked as a party of 14 (2 x grand-parents, 4 x 30/40 somethings (parents, of which I was one) and 6 x grandchildren (ranging from 9-24, some with partners)).
A variety of ages therefore were required to be catered for... the Oceana seemed to fit the bill - many of the family have cruised before, some more than a few times, and historically with the P&O ship 'Canberra' but I never had.
We had a variety of room types between us, one suite (Orcades B755), two mini suites (B321 & B309) and a few inner rooms on B deck.
The cabin was great! double bed, fold out sofa bed, 2 x TV's, shower, bath, make-up desk, Wi-Fi signal was slow but consistent, the balcony (and the view, was fantastic), I slept there for 2 nights!
