Firstly let me say we were so frightened after having booked this cruise last minute then read the feedback on here. We thought we were going on a shabby tired ship in need of urgent refit.
Secondly, I dont think its any shock the P&O Oriana is a P&O ship, not a Cunard one, Royal Caribbean or any other others blocks of flats which float. Its a characterful ship of some age, offered at a very good price (I assume CUnard Royal Caribbean fans booked this cruise on price - otherwise they'll have booked on their favoured mode of transport!
We got this cruise @£50 pppn. which is an absolute bargain.
