Having just completed the P&O j219 cruise on Arcadia to the Greek islands with a stop at Malaga on the way out and Gib on the way back, I will give you the gen. Firstly we have only ever been with Cunard before this, so that is the benchmark I am working from, some facts..
£6400 for a deluxe balcony £3200 each.

In February this year we did a Carribean 28 night cruise for £3000 each.. just over £100 per night, whereas j219 was over £150 a night…
